Ada 8 kotak hadiah. 5 kotak berwarna merah. Berapakah pecahan kotak merah?
一组物件的分数 = pecahan sekumpulan objek
数一数一共有几个盒子,写在横线下面;再数红色的盒子,写在横线上面。图里的绿色盒子不用算进分子,但要算进总数。
例子:6 个气球中 1 个白色 → 1/6。
注意:把总数写在上面,分数就倒过来了。
fraction of a group = pecahan sekumpulan objek
Count all the boxes and write that number below the line; then count the red boxes and write that number on top. The green boxes are not in the numerator, but they are part of the total.
Example: 1 of 6 balloons is white → 1/6.
Watch out: writing the total on top turns the fraction upside down.
Tujuh persembilan ditulis sebagai …
写出分数 = tulis pecahan
先听第一个数字,它是分子,写在上面;再听 per 后面的字,它告诉你分母。persembilan 表示分母是 9。
例子:dua perlapan → 2/8;lima pertujuh → 5/7。
注意:persembilan(9)和 persepuluh(10)听起来很像,要分清楚。
writing a fraction = tulis pecahan
Listen for the first number: it is the numerator and goes on top. The word after per tells you the denominator; persembilan means the denominator is 9.
Example: dua perlapan → 2/8; lima pertujuh → 5/7.
Watch out: persembilan (9) and persepuluh (10) sound alike, so listen carefully to tell them apart.
Dalam pecahan 610, nombor 10 dipanggil …
分数各部分的名称 = nama bahagian pecahan
分数有上下两个数:一个告诉我们整体一共分成几份,另一个告诉我们取了几份。先看 10 写在横线的哪一边,想一想它表示什么,再选出它的名称。
例子:在 3/8 里,3 表示取了 3 份,叫 pengangka。
注意:pecahan wajar 是整个分数的名称,不是其中一个数。
names of the parts = nama bahagian pecahan
A fraction has two numbers: one tells how many equal parts the whole is cut into, and the other tells how many parts are taken. Check which side of the line the 10 is on, think about what it tells you, then choose its name.
Example: in 3/8, the 3 tells that 3 parts are taken, so it is the pengangka.
Watch out: pecahan wajar names a whole fraction, not one of its numbers.
Pecahan manakah bukan pecahan wajar?
不是真分数 = bukan pecahan wajar
真分数的分子比分母小,值小于 1。要找“不是”的那一个,就找分子大于或等于分母的分数。这样的分数已经有 1 个整体或更多。
例子:7/3 的分子 7 比分母 3 大 → 不是真分数。
注意:题目里有 bukan,要选“不符合”的,不要选到真分数。
not a proper fraction = bukan pecahan wajar
A proper fraction has a numerator smaller than its denominator, so it is worth less than 1. To find the one that is not proper, look for a numerator equal to or bigger than the denominator; that fraction is already one whole or more.
Example: in 7/3 the numerator 7 is bigger than 3 → not proper.
Watch out: the question says bukan, so pick the one that breaks the rule.
Dalam satu kumpulan ada 10 orang murid. 6 orang murid perempuan. Berapakah pecahan murid lelaki?
先求另一部分 = cari bahagian lain dahulu
题目给的是女生人数,问的却是男生。先用总人数减去女生:得到男生人数,当作分子。分母仍然是全组的人数。
例子:8 位老师中 5 位女老师 → 男老师 3 位 → 3/8。
注意:拿男生和女生互相比,分母就错了。
find the other part first = cari bahagian lain dahulu
The question gives the number of girls but asks about the boys. Subtract the girls from the whole group to get the boys, and use that as the numerator. The denominator is still the whole group.
Example: 5 of 8 teachers are women → 3 are men → 3/8.
Watch out: comparing boys with girls puts the wrong number in the denominator.
Nilai sesuatu pecahan wajar sentiasa … 1.
真分数的大小 = nilai pecahan wajar
真分数的分子比分母小,代表一个整体里只取了一部分,还没有取完,所以它的值一定比 1 小。把整条长条全部涂满才是 1。
例子:9/10 很接近 1,但还差 1/10 才是 1。
注意:分子大的真分数也还是小于 1。
size of a proper fraction = nilai pecahan wajar
A proper fraction has a numerator smaller than its denominator, so only some of the parts of one whole are taken. That is why its value is always under 1; only a fully shaded strip makes 1.
Example: 9/10 is very close to 1, but it is still 1/10 short.
Watch out: even a proper fraction with a big numerator is still less than 1.
Ibu membeli 7 biji telur itik. 2 biji retak. Berapakah pecahan telur yang tidak retak?
没有破的部分 = bahagian yang tidak retak
题目问“没有裂开的”,先用总数 7 减去裂开的 2 颗,得到没有裂开的颗数,当作分子;分母是全部鸭蛋的数目。
例子:5 个苹果中 1 个烂了 → 好的 4 个 → 4/5。
注意:2/7 是裂开的部分,不是题目要的。
the uncracked part = bahagian yang tidak retak
The question asks about eggs that are not cracked. Take the 2 cracked eggs away from all 7 to get the numerator; the denominator is the total number of duck eggs.
Example: 1 of 5 apples is rotten → 4 are good → 4/5.
Watch out: 2/7 is the cracked part, which is not what the question asks.
