Santai Minda
Langkah 1

Padankan nilai

Cari pasangan pecahan persepuluh dan perpuluhan yang menunjukkan nilai sama.

2/10 ↔ 0.2
Padankan nilai = 配对相同的值
把分母是10的分数和小数配对,找出值一样的一组。2/10 的分子是2,所以配 0.2。分子和小数点后的数字相同,就是一对。例子:卡片上有 6/10、0.6 和 0.9,6/10 与 0.6 是一对。注意:配对前先确认分母是10,分母是100的分数不能这样配。
Padankan nilai = match the values
Match each tenths fraction to the decimal with the same value. In 2/10 the numerator is 2, so its partner is 0.2. When the numerator equals the digit after the point, the pair matches. Example: cards show 6/10, 0.6 and 0.9; 6/10 and 0.6 form a pair. Watch out: check that the denominator is 10 first, because hundredths do not match this way.
Langkah 2

Banding dengan yakin

Tukar kepada bentuk sama atau gunakan garis nombor sebelum memilih nilai lebih besar.

tukar → banding → semak
Banding dengan yakin = 有把握地比较
比较前先统一写法:把分数改成小数,或把两数放在数线上。写法一样后,只看十分位数字就能判断,最后再看数线确认。例子:比较 3/10 和 0.8,3/10 是3个十分之一,8个比3个多,所以 0.8 较大。注意:没有先改写就凭感觉选,最容易出错。
Banding dengan yakin = compare with confidence
Make both numbers the same form first, either as decimals or as points on a number line. Once they match in form, the tenths digit decides which is bigger. Then glance at the number line again to confirm. Example: compare 3/10 and 0.8; 3/10 is 3 tenths, and 8 tenths is more, so 0.8 is larger. Watch out: guessing without converting first causes most mistakes.
Langkah 3

Terangkan pilihan

Sebut sebab jawapan betul menggunakan pengangka, penyebut, digit persepuluh atau kedudukan pada garis nombor.

jawapan + sebab
Terangkan pilihan = 说明选择的理由
答对后还要说出理由:分子和分母是几、十分位数字是几,或在数线上哪个点更靠右。这样才知道你真的懂。例子:6/10 比 0.2 大,因为 6/10 是6个十分之一,0.2 只有2个十分之一。注意:只说“它比较大”不算理由,一定要提到数字或位置。
Terangkan pilihan = explain your choice
After choosing, say why. Mention the numerator and denominator, the tenths digit, or which point sits further right on the number line. A reason shows you really understand. Example: 6/10 is bigger than 0.2 because 6/10 is six tenths while 0.2 is only two tenths. Watch out: saying it is bigger is not a reason; you must name a number or a position.

Pasangan manakah sama nilai?

Sama nilai = 值相同
题目给了三组数,要找出分数和小数值一样的那一组。线索:分子要等于小数点后的数字。每一组都检查一次,再用数线看两个点是否重合。例子:9/10 和 0.9 是一对,9/10 和 0.1 就不是。注意:几组里会出现相同的数字,别只看一边就决定。
Sama nilai = same value
You see three pairs and must find the pair where the fraction and decimal are equal. The clue is that the numerator must equal the digit after the point. Test every pair, then check on a number line whether the two points meet. Example: 9/10 and 0.9 match, but 9/10 and 0.1 do not. Watch out: digits repeat across pairs, so check both numbers, not just one side.

Pecahan wajar manakah paling besar?

Pecahan wajar paling besar = 最大的真分数
三个分数的分母都是8,题目问哪个最大。分母相同时,每一份一样大,只要比分子,分子越大分数越大。也可以画一个分8份的长条来检查。例子:1/5、4/5、3/5 中,4/5 最大,因为它的份数最多。注意:分母一样时不要去比分母,要比上面的分子。
Pecahan wajar paling besar = largest proper fraction
All three fractions have 8 as the denominator, and you must find the largest. When denominators match, every part is the same size, so the bigger numerator means the bigger fraction. Draw a bar cut into 8 parts to check. Example: among 1/5, 4/5 and 3/5, 4/5 is largest because it has the most parts. Watch out: compare the top numbers here, not the matching bottom numbers.
