Untuk menjawab 24 ÷ 6, fikirkan 6 darab berapa menjadi 24.

Santai Minda
Langkah 1

Cari fakta darab

Untuk menjawab 24 ÷ 6, fikirkan 6 darab berapa menjadi 24.

6 × 4 = 24 → 24 ÷ 6 = 4
Cari fakta darab = 找乘法事实
做除法时,可以反过来想乘法。算 24 ÷ 6,就问自己“6 乘几等于 24?”因为 6 × 4 = 24,所以 24 ÷ 6 = 4。乘法表背得熟,除法就算得快。
例子:36 ÷ 9:9 × 4 = 36,所以 36 ÷ 9 = 4。
注意:要找的是乘法里缺少的那个数,不是把看到的两个数相乘。
Cari fakta darab = Find the multiplication fact
To divide, think of multiplication backwards. For 24 ÷ 6, ask yourself: six times what makes 24? Since 6 × 4 = 24, the answer is 24 ÷ 6 = 4. Knowing your tables well makes division quick.
Example: 36 ÷ 9: 9 × 4 = 36, so 36 ÷ 9 = 4.
Watch out: You are looking for the missing factor, not multiplying the two numbers you see.
Langkah 2

Baca ayat bahagi

Kenal pasti nombor yang dibahagi dan saiz atau bilangan kumpulan.

jumlah ÷ kumpulan = setiap kumpulan
Baca ayat bahagi = 读懂除法句子
读除法题时,先找“一共有多少”,这个数放在除号前面。再看题目给的是“分成几组”还是“每组几个”,这个数放在除号后面。算出来的就是另外一个。
例子:28 张卡片平均分给 4 个人,每人几张?28 ÷ 4 = 7 张。
注意:总数一定写在除号前面,不能把小的数写在前面。
Baca ayat bahagi = Read the division sentence
First find the total, because it goes before the division sign. Then see whether the question gives the number of groups or the size of each group; that number goes after the sign. The answer is the other one.
Example: 28 cards are shared equally among 4 children. Each child gets 28 ÷ 4 = 7 cards.
Watch out: The total always comes first in a division; never put the smaller number in front.
Langkah 3

Semak jawapan

Darabkan jawapan dengan pembahagi untuk memastikan nombor asal diperoleh.

jawapan × pembahagi = nombor asal
Semak jawapan = 检查答案
除法做完后,用“答案 × 除数”来检查。乘出来等于原来的数,就证明答案对。这个方法每次都能用,又快又准。
例子:45 ÷ 5 = 9,检查 9 × 5 = 45,正确。
注意:如果乘出来不对,先检查乘法表有没有背错,再重新除。
Semak jawapan = Check the answer
After dividing, multiply the answer by the divisor. If you get the starting number again, the answer is correct. This check works every time and is quick to do.
Example: 45 ÷ 5 = 9. Check: 9 × 5 = 45, correct.
Watch out: If the check does not match, first make sure you remembered the times table correctly, then divide again.

8 ÷ 8 = __

Bahagi dengan diri sendiri = 自己除以自己
题目问 8 ÷ 8,就是 8 个东西每 8 个一组,能分成几组。也可以想:8 乘几等于 8?用乘法反过来检查,就知道哪个选项成立。
例子:6 ÷ 3 = 2,因为 2 × 3 = 6。
注意:先认清符号是 ÷,再用分组的方法来想。
Bahagi dengan diri sendiri = A number divided by itself
The question asks for 8 ÷ 8: put 8 objects into groups of eight and count how many groups you get. You can also ask: eight times what makes 8? Checking with multiplication tells you which choice works.
Example: 6 ÷ 3 = 2, because 2 × 3 = 6.
Watch out: Look at the sign first; it is division, so think about making groups.

9 ÷ 3 = __

Bahagi 9 dengan 3 = 9 除以 3
题目问 9 ÷ 3,意思是 9 个东西平均分成 3 份,每份有几个。可以画 9 个点,一个一个轮流放进 3 个圈,再数一个圈里有几点。也可以想:几乘以 3 等于 9?
例子:8 ÷ 2 = 4,两个圈各放 4 点,正好用完 8 点。
注意:画完后看看每个圈的点数是不是一样多,不一样就重新分。
Bahagi 9 dengan 3 = Nine divided by three
The question asks for 9 ÷ 3: share 9 objects equally into 3 parts and find each part. Deal 9 dots one by one into 3 circles and count one. Or ask: what number times 3 makes 9?
Example: 8 ÷ 2 = 4, since two circles of four dots use up all 8 dots.
Watch out: Every circle must end with the same number of dots; if not, share again.
