​Hello! Today we'll be learning about Dividing fractions by integers. If you don't know then its ok. You might have learned fractions before in year 6.

Dividing fractions by integers is basically a fraction divided by a number

​

​

Example: 8

​

​

​10

​÷

​2

​To solve this, you need to look at the integer which is this one

On computer I just do this 8/10

​So 2 is just 2 but in fractions it is 2 over 1 (2/1)

So it'll be 8/10 divided by 2/1. Let's look at this question:

​

8/10 ÷ 2/1

​

To solve this what you have to do is to switch the numerator (2) and the denominator ​(1) so it'll be like this: 1/2, but when you do that, from the division, it will turn to multiply so you have to multiply: 8/10 ÷ 2/1 = 8/10 x 1/2= 8/20. You might be asking...are done?? well truly no because you have to divide 8/20 and it's called 'Simplify'.

​To simplify, all you got to do is just to divide 8/20 by 2 because the integer in this question is 2. And you need to divide the numerator and denominator: 8/20 ÷​ 2 = 4/10. But we can still simplify!! 4/10 ÷ 2 = 2/5 and that's it. This is how you do divide fractions by integers. If you want the full calculations then go to next slide ->

​8/10 ÷ 2/1 = 8/10 x 1/2 = 8/20 ÷ 2 = 4/10 ÷ 2 = 2/5
