Bagaimana kita menulis 27 daripada 100?

Kenal Pecahan Perseratus dan Perpuluhan
perseratus = 百分之几 整体平均分成 100 份,取其中几份,就是“百分之几”。百格图刚好有 100 小格,涂了几格就是百分之几,可以写成分数,也可以写成小数。 例子:一盒 100 颗纽扣,有 12 颗是绿色 → 12/100,也就是 0.12。 注意:整体一定要是 100 个相等的部分,才能这样表示。
hundredths = perseratus When one whole is split into 100 equal parts, each part is one hundredth. A hundred square has exactly 100 small squares, so the number of coloured squares tells us how many hundredths we have. We can write it as a fraction or as a decimal. Example: a box holds 100 buttons and 12 are green → 12/100, which is 0.12. Watch out: the whole must have 100 equal parts before we can use hundredths.
Pecahan perseratus

27 daripada 100

Dua puluh tujuh perseratus

27/100=0.27
27 daripada 100 = 27 per 100

dua puluh tujuh perseratus

pecahan perseratus = 分母是 100 的分数 涂了 27 格,整体有 100 格,所以写成 27/100,读作 dua puluh tujuh perseratus。分子是涂色的格数,分母是全部的格数。 例子:100 张贴纸里有 65 张是星星 → 65/100。 注意:分母永远写 100,不要把 100 写在分子上。
fraction in hundredths = pecahan perseratus 27 squares are coloured out of 100, so we write 27/100 and say dua puluh tujuh perseratus. The numerator 27 counts the coloured squares; the denominator 100 counts all the squares. Example: 65 of 100 stickers are stars → 65/100, said enam puluh lima perseratus. Watch out: 100 always goes at the bottom as the denominator, never on top.
Perpuluhan

Pecahan dan perpuluhan

Dua cara menulis nilai yang sama

pecahan perseratus

27 per 100

perpuluhan

0.27

titik perpuluhan

0.27
27 per 100 = 0.27
perpuluhan = 小数;titik perpuluhan = 小数点 27/100 也可以写成小数 0.27。小圆点叫小数点:左边是个位,右边第一位是十分位,第二位是百分位。分母是 100 的分数,写成小数时点后有两位数字。 例子:83/100 = 0.83。 注意:小数点要写在个位的右下方,不可漏写,也不要写成逗号。
decimal = perpuluhan; decimal point = titik perpuluhan 27/100 can also be written as the decimal 0.27. The small dot is the decimal point: on its left is the ones place (0 here), and on its right come the tenths and then the hundredths. A fraction over 100 becomes a decimal with two digits after the point. Example: 83/100 = 0.83. Watch out: never leave out the point, and do not write a comma instead.

sifar · perpuluhan · dua · tujuh

✗ sifar perpuluhan dua puluh tujuh

sebut perpuluhan = 读小数 用马来文读小数时,小数点读作 perpuluhan,点后面的数字要一个一个地读。0.27 读作 sifar perpuluhan dua tujuh。 例子:0.94 的点后读作 sembilan empat。 注意:点后不能读成“二十七”这样的整数。
saying decimals = sebut perpuluhan In Malay we say the part before the point as usual, say perpuluhan for the point, and then say each digit after it one by one. So 0.27 is sifar perpuluhan dua tujuh. Example: 0.94 is said sifar perpuluhan sembilan empat. Watch out: do not read the digits after the point as one whole number like twenty-seven; say them separately.

Petak jingga mewakili perpuluhan apa?

kira petak = 数格子 先数涂色的格子:每一整行是 10 格,几整行就是几个十,再加上零散的格子。数出来的数就是百分之几,再把它写成小数点后两位的小数。 例子:涂了 5 整行再加 2 格 → 52 格 → 0.52。 注意:两个数字的次序不可颠倒,十位的数字写在小数点后第一位。
count the squares = kira petak First count the coloured squares: each full row is 10, so count the full rows as tens and add the extra squares. That number of hundredths is then written with two digits after the decimal point. Example: 5 full rows and 2 more squares → 52 squares → 0.52. Watch out: keep the digits in order; the tens digit goes straight after the point.
Perseratus yang kecil

6 daripada 100

Satu digit sahaja

6 per 100 = 0.06
sa•persepuluhperseratus
0•06
persepuluh = 十分位;perseratus = 百分位 只涂 6 格,是 6 个百分之一,所以 6 写在百分位。十分位没有数,必须写 0 占位,得到 0.06。位值表能帮我们把数字放对位置。 例子:2/100 = 0.02。 注意:写成 0.6 就变成 60 格了,十分位的 0 不能省略。
tenths = persepuluh; hundredths = perseratus With only 6 squares coloured, we have 6 hundredths, so the 6 belongs in the hundredths place. The tenths place is empty and needs a 0 as a placeholder, giving 0.06, said sifar perpuluhan sifar enam. A place value table helps us put each digit in the right place. Example: 2/100 = 0.02. Watch out: 0.6 would mean 60 squares; the 0 in the tenths place cannot be dropped.

1 per 100 dalam perpuluhan ialah …

一个百分之一 = satu perseratus 分子只有一位数时,想一想它应该放在哪一位:百分之几的数字要放在小数点后的第二位,也就是百分位。前面的十分位要补 0,个位也写 0。 例子:5/100 → 个位 0,十分位 0,百分位 5 → 0.05。 注意:1 若写在点后第一位,就变成十个百分之一了。
one hundredth = satu perseratus When the numerator has only one digit, think about where it belongs: hundredths go in the second place after the point. Put 0 in the tenths place and 0 in the ones place in front of it. Example: 5/100 → ones 0, tenths 0, hundredths 5 → 0.05. Watch out: a 1 written straight after the point would mean ten hundredths instead.
Warnakan petak

Tunjukkan perpuluhan pada petak 100

0.35 dan 0.05

0.35
0.05
涂色表示小数 = warnakan perpuluhan 反过来,看到小数也能涂百格图:小数点后两位数字合起来是几,就涂几格。0.35 是 35 格,先涂 3 整行,再涂 5 格;0.05 只涂 5 格。 例子:0.71 → 涂 7 整行再加 1 格。 注意:0.35 和 0.05 只差一个数字,涂的格数却差了 30 格,要看清十分位。
colouring a decimal = warnakan perpuluhan We can also go the other way: read the two digits after the point together and colour that many squares. 0.35 means 35 squares, so colour 3 full rows and then 5 more; 0.05 means only 5 squares. Example: 0.71 → colour 7 full rows and 1 more square. Watch out: 0.35 and 0.05 differ by one digit but by 30 squares, so look carefully at the tenths digit.

Klik petak atau tambah satu petak dan satu baris. Lihat tiga bentuk nombor berubah bersama.

百格图 = grid 100;百分数 = peratus;小数 = perpuluhan 实验台有 100 个小格。你可以直接点格子,或每次增加 1 格、1 行。右边同时显示涂色格数占一百的分数、小数和百分数;三种写法都表示同一个部分。完成 27、6、40 格三个目标。 例子:涂 6 格时,小数要保留两个小数位,所以写 0.06。 注意:一整行有 10 格,按“增加一行”就是加 10,不是加 1。
hundred grid = grid 100; percentage = peratus; decimal = perpuluhan The lab has 100 small squares. Click a square directly, or add one square or one full row at a time. The right side shows the coloured part as a fraction in hundredths, a decimal and a percentage; all three forms describe the same part. Complete targets of 27, 6 and 40 squares. Example: with 6 squares coloured, keep two decimal places and write 0.06. Watch out: one full row contains 10 squares, so adding a row adds 10, not 1.
Semak makmal

Apakah yang berubah apabila satu baris penuh ditambah?

一整行 = satu baris penuh;增加 = bertambah 题目要你判断百格图增加一整行时,涂色格数增加多少。回想实验台每行横向排列的小格数量,或亲自从左到右数一行。选择表示格数变化的选项,不是小数或百分数的写法。 例子:可以先把一行分成两个相同的五格组,再合起来计算。 注意:题目问“格数增加多少”,不要把整张图的 100 格当成新增数量。
one full row = satu baris penuh; increases = bertambah The question asks how many coloured squares are added when one complete row is added. Recall the number of small squares laid across each row in the lab, or count a row from left to right. Choose the change in square count, not a decimal or percentage notation. Example: split one row into two equal groups of five and combine them. Watch out: the question asks how many squares are added, not how many squares the entire grid contains.
Betulkan yang salah

Sebutan yang betul

0.50 dan 0.13

0.50 → sifar perpuluhan lima puluh
✓ sifar perpuluhan lima sifar
0.13 → sifar perpuluhan tiga belas
✓ sifar perpuluhan satu tiga
改正读法 = betulkan sebutan 读小数最常见的错,是把点后的两位数当成一个整数来读。0.50 后面的 0 也要读出来,读作 lima sifar;0.13 要逐个读 satu tiga。 例子:0.90 的点后读作 sembilan sifar。 注意:小数点后面出现 belas 或 puluh,就是读错了。
fixing how we say it = betulkan sebutan The most common mistake is reading the two digits after the point as one number. 0.50 is said sifar perpuluhan lima sifar, saying the final 0 too, and 0.13 is said sifar perpuluhan satu tiga. Example: 0.90 is said sifar perpuluhan sembilan sifar. Watch out: if you hear belas or puluh after perpuluhan, the reading is wrong.
Padankan

Kad perkataan dan kad angka

kad perkataan = 文字卡;kad angka = 数字卡 文字卡有两种:有 perpuluhan 的是小数的读法,要逐个数字对应;有 perseratus 的是分数的读法,读出的数是分子,分母是 100。 例子:dua puluh perseratus → 20/100。 注意:小数读法里紧跟在点后的 sifar,表示十分位是 0。
word card = kad perkataan; number card = kad angka There are two kinds of words. Words with perpuluhan read a decimal, so match each digit in turn. Words with perseratus read a fraction: the number said is the numerator and the denominator is 100. Decide which kind first, then find its partner. Example: sifar perpuluhan empat lapan → 0.48; dua puluh perseratus → 20/100. Watch out: sifar right after perpuluhan means the tenths digit is 0.
Bahagian tidak berwarna

Petak putih pun boleh ditulis

100 − 31 = 69

100 − 31 = 69
putih: 69 per 100 = 0.69
没涂色的部分 = bahagian tidak berwarna 全部有 100 格,减去涂色的格数,就是白色的格数。31 格涂色,白色有 100 − 31 = 69 格,写成 69/100 = 0.69。涂色和白色合起来一定是 100 格。 例子:涂了 15 格 → 白色 85 格 → 0.85。 注意:100 − 31 要退位小心,答案不是 79。
the part not coloured = bahagian tidak berwarna The whole has 100 squares, so take away the coloured squares to find the white ones. With 31 coloured, there are 100 − 31 = 69 white squares, written 69/100 = 0.69. The coloured and white parts always add up to 100. Example: 15 coloured → 85 white → 0.85. Watch out: subtract carefully when regrouping; 100 − 31 is not 79.

Apakah perpuluhan bagi petak putih?

白色部分的小数 = perpuluhan bagi petak putih 要求白色的部分,先数橙色有几格,再用 100 减去它,得到白色的格数,最后写成两位小数。做完可以检查:两部分加起来要等于 100。 例子:橙色 22 格 → 白色 78 格 → 0.78。 注意:100 减去一个数时,个位不够减要向十位借,十位要少 1。
decimal for the white part = perpuluhan bagi petak putih To find the white part, first count the orange squares, take them away from 100 to get the white squares, then write a two-digit decimal. Check that the two parts add to 100. Example: 22 orange → 78 white → 0.78. Watch out: when taking a number from 100, borrow for the ones, so the tens digit becomes one less.
Bina perpuluhan

Tujuh perseratus dalam perpuluhan

排出小数 = bina perpuluhan 按位置排:先排个位,再排小数点,然后是十分位,最后是百分位。七个百分之一只有百分位有数字,十分位要放 0 占位。排好以后,从左到右读一遍检查。 例子:四个百分之一 → 个位 0、小数点、十分位 0、百分位 4。 注意:有一张多余的卡,用不到的卡不要放进去。
build the decimal = bina perpuluhan Place the cards in order: ones first, then the decimal point, then tenths, then hundredths. Seven hundredths has a digit only in the hundredths place, so the tenths place needs a 0 as a placeholder. Read it from left to right to check. Example: four hundredths → ones 0, point, tenths 0, hundredths 4. Watch out: there is one extra card; leave out the card you do not need.
