Play with the Idea

Try changing the values here ... sometimes there will be a remainder:

But Sometimes It Does Not Work Perfectly!

Sometimes you cannot divide things up evenly ... there may be something left over.

Example: There are 7 cookies, and 2 people want to share them equally.

But 7 cookies cannot be divided exactly into 2 groups,
each person gets 3 cookies,
but there will be 1 left over:

We call that the Remainder. 



We say:

"7 divided by 2 equals 3 with a remainder of 1"

And we write:

7 ÷ 2 = 3 R 1

 

As a Fraction

It is also possible to cut the remaining cookie in half, and then each person would have 3 ½ cookies, so:

7 ÷ 2 = 3 R 1 = 3 ½

"7 divided by 2 equals 3 remander 1 equals 3 and a half"

Opposite of Multiplying

Division is the opposite of multiplying. If you know a multiplication fact you can find a division fact:

Example: 3 × 5 = 15, so 15 / 5 = 3.

Also 15 / 3 = 5.

Why? Well it is easy to understand if you think of the numbers in rows and columns like in this illustration:

Multiplication... ...Division 3 groups of 5 make 15... so 15 divided by 3 is 5 and also: 5 groups of 3 make 15... so 15 divided by 5 is 3.

So there are four related facts:

• 3 × 5 = 15
• 5 × 3 = 15
• 15 / 3 = 5
• 15 / 5 = 3

Knowing your Multiplication Tables can help you with division!

Example: What is 56 ÷ 7 ?

Searching around the multiplication table you find that 56 is 7 × 8, so 56 divided by 7 must be 8. Answer: 56 ÷ 7 = 8.

Division - Introduction

Pengenalan kepada proses pembahagian di dalam Matematik.

Division

Division is splitting into equal parts or groups. It is the result of "fair sharing".

Example: there are 12 chocolates, and 3 friends want to share them, how do they divide the chocolates?

12 Chocolates		12 Chocolates Divided by 3

Answer: 12 divided by 3 is 4: they get 4 each.

Symbols

÷ /	We use the ÷ symbol, or sometimes the / symbol to mean divide: 12 ÷ 3 = 4 12 / 3 = 4 I will use both symbols here so you get used to it.

Konsep Bahagi

Memahami Konsep Bahagi

Memperkenal konsep bahagi kepada anak-anak kadangkala mendatangkan masalah. Berikut adalah video yang dapat membantu kita dalam memudahkan pemahaman anak2 dalam  menyelesaikan operasi yang melibatkan operasi pembahagian. Selain itu video ini dapat membantu guru2 dalam menjayakan proses Pengajaran dan Pembelajaran tentang tajuk bahagi.

Operasi Bahagi

Sebuah syarikat percetakan ingin menderma buku sebanyak 12300 buah kepada 30 buah sekolah di sekitar Kuala Lumpur. Berapa buah bukukah akan diterima oleh setiap sekolah ?

Kata kunci : 12300 buah buku

 'dibahagikan sama rata kepada'   

30 buah 

Penyelesaian : 

12300 buah buku akan diberi sama rata kepada 30 buah sekolah.

Jadi, setiap sekolah akan menerima 410 buah buku.

12300  30 = 410
