bandingkan dengan 30% = 跟 30% 比较 三张卡有小数也有分数,样子不一样,大小却可能相同。把每张卡都改写成几个百分之一,再跟 30% 比较:30% 就是 30 个百分之一。 例子:0.5 和 5/10 都是 50 个百分之一,都等于 50%。 注意:要看数字 3 在十分位还是百分位。
bandingkan dengan 30% = compare with 30% The three cards mix decimals and a fraction, so they look different, but some may have the same value. Rewrite every card as a number of hundredths and compare it with 30%, which is 30 hundredths. Example: 0.5 and 5/10 are both 50 hundredths, so both equal 50%. Watch out: check whether the 3 is in the tenths place or the hundredths place.

Farah, Wei Ling: 30%
Ben: 3%
tukar kepada perseratus = 化成百分之几 0.3 是 3 个十分之一,1 个十分之一等于 10 个百分之一,所以 0.3 = 30/100 = 30%。3/10 也是 3 个十分之一,同样等于 30%。0.03 的 3 在百分位,只有 3/100 = 3%。 例子:0.4 = 4/10 = 40%,0.04 = 4%。 注意:紧跟小数点的 0 会改变大小。
tukar kepada perseratus = change to hundredths 0.3 is 3 tenths, and one tenth equals 10 hundredths, so 0.3 = 30/100 = 30%. The fraction 3/10 is also 3 tenths, so it equals 30% too. In 0.03 the 3 is in the hundredths place, so it is only 3/100 = 3%. Example: 0.4 = 4/10 = 40%, but 0.04 = 4%. Watch out: a zero right after the point changes the value.
Jawab cabaran

Dua kad manakah sama dengan 80%?

0.088 per 100.8
dua kad sama nilai = 两张等值的卡 先把目标百分数写成几个百分之一。再把每张卡都改写成百分之几:小数要看数字在哪一位,十分之几的分数就是几个十分之一。和目标一样多的两张卡,就是答案。 例子:哪两张等于 20%?0.2 和 2/10 都是 20/100,0.02 只有 2/100。 注意:卡上有相同的数字,不代表大小一样。
dua kad sama nilai = two cards with equal value First write the target percentage as hundredths. Then rewrite each card as hundredths: for a decimal, check the place of each digit; a fraction in tenths is that many tenths. The two cards that match the target are the answer. Example: which two equal 20%? 0.2 and 2/10 are both 20/100, but 0.02 is only 2/100. Watch out: cards showing the same digit are not always the same size.
Cuba lagi

Nyatakan 0.2 dalam peratus.

perpuluhan satu tempat kepada peratus = 一位小数化百分数 只有一位小数时,先在末尾补一个零,变成两位小数,大小不变。再把小数点后的两个数字看成几个百分之一,加上 % 号。 例子:0.6 → 0.60 → 60%。 注意:不补零就直接写百分数,会把十分位看成百分位。
perpuluhan satu tempat kepada peratus = one-place decimal to percent With only one decimal place, first add a zero at the end to make two places; the value does not change. Then read the two digits after the point as hundredths and add the % sign. Example: 0.6 → 0.60 → 60%. Watch out: writing a percentage without adding the zero treats the tenths digit as hundredths.
Ringkasan

Syabas!

0.3 = 3 per 10 = 30%
0.03 = 3%

Tukar setiap nombor kepada perseratus sebelum membanding. Sifar selepas titik perpuluhan mengubah nilai; sifar di hujung tidak mengubah nilai.
