The first step is to multiply the two numerators (the top number of the fraction). The second step is to multiply the two denominators (the bottom number of the fraction). Then if the question asks you to simply it you see what numbers goes into your answ
1 of 5
2x+4=8
you minus the 4 from the 8 because you reverse the +4 to a minus 4 and that gets you positive 4. Then you divide the 4 by the 2 to make 2.
Remember, always put x = your answer so in this example it would be x = 2

A packet of biscuits costs 56p.
A bottle of cola costs £1.14
Emma buys 4 packets of biscuits and one bottle of cola.
She pays with a £10 note.
Work out how much change she should get.
So for this question all you do is 0.56 x 4 = £2.24
Then we add the £2.24 and the £1.14 to make £3.38.
We get told she pays with a £10 note and wants to know how much change she would get so you do
£10 - £3.38 =£6.62
Emma has £6.62 change back.

When making yoghurt, the ratio of starter yogurt to milk should be 1:9. I want to make 1000ml of yoghurt. How much milk should I use?
Here we know the full amount – 1000ml.
The ratio is 1:9 and we want to find the amount of milk.
Total number of shares = 1 + 9 = 10
Value of each share: 1000 ÷ 10 = 100
The milk is 9 shares so 9 × 100 = 900
