maklumat penting = 重要资料 解题前先找三样东西:整体是什么、平均分成几份、用了或选了几份。份数做分母,用掉的份数做分子。例子:一块蛋糕平均切8块,吃了3块,分母是8,分子是3,写成 3/8。注意:每份要一样大才能写分数,大小不一的份不能直接算。
maklumat penting = important information Before solving, find three things: the whole, how many equal parts it has, and how many parts are used or chosen. The number of parts becomes the denominator and the used parts become the numerator. Example: a cake is cut into 8 equal slices and 3 are eaten, so the fraction eaten is 3/8. Watch out: the parts must be equal in size before you can write a fraction.
Langkah 2
Pilih perwakilan
Gunakan rajah, garis nombor atau pertukaran persepuluh kepada perpuluhan mengikut soalan.
Pilih perwakilan = choose a representation Pick the tool that fits the question: a diagram to show parts, a number line to compare sizes, or a tenths-to-decimal change when a decimal answer is needed. Choosing well makes the working clearer. Example: if asked to write 5/10 as a decimal, simply change it to 0.5 without drawing. Watch out: only wholes cut into 10 parts change straight into decimals; a shape cut into 6 parts does not.
Langkah 3
Semak jawapan
Pastikan pecahan wajar kurang daripada satu dan perbandingan sepadan dengan rajah.
Semak jawapan = check the answer After answering, check two things. A proper fraction has a top number smaller than the bottom number, so it is less than one whole. Your comparison must also agree with the shaded parts in the diagram. Then explain your reason in one sentence. Example: 2/5 shaded means 2 is less than 5, so the value is below 1. Watch out: writing 5/2 means you flipped the numerator and denominator.

Aina mewarna 4 daripada 9 bahagian sama besar. Pecahan berwarna ialah…
Pecahan berwarna = 涂色部分的分数 题目说 Aina 把平均分成9份的图形涂了其中一些,要写出涂色部分的分数。线索:总份数放下面做分母,涂色份数放上面做分子。例子:一个披萨分6份,涂了5份,涂色部分是 5/6。注意:题目问的是涂色部分,不要去算没涂色的那几份。
Pecahan berwarna = shaded fraction Aina colours some of 9 equal parts, and you must name the coloured fraction. Clues: the total number of parts goes at the bottom as the denominator, and the coloured parts go on top as the numerator. Example: a pizza has 6 equal slices and 5 are coloured, so the coloured fraction is 5/6. Watch out: the question asks for coloured parts, not the uncoloured ones.

Sebuah reben dibahagi 10 bahagian. Tiga bahagian digunakan. Dalam perpuluhan, bahagian digunakan ialah…
Dalam perpuluhan = 用小数表示 丝带平均分成10份,用了其中几份,题目要你用小数写出用掉的部分。先写成十分之几的分数,再把分子放在小数点后第一位。例子:一条绳子分10份,用了8份,是 8/10,也就是 0.8。注意:十分之几的小数前面是0,不要把份数写在小数点前面。
Dalam perpuluhan = in decimals A ribbon is cut into 10 equal parts and some are used. Write the used part as a decimal. First write it as a tenths fraction, then put the numerator in the first place after the decimal point. Example: a rope has 10 parts and 8 are used, so 8/10 = 0.8. Watch out: a tenths decimal starts with 0, so the number of parts never goes before the point.
