38.5g of sugar is needed to make 5 cakes. How much sugar is needed for 7 cakes?

53.9g

Step-by-step explanation:

As you can't end up with a whole number by doing 7 divided by 5, first work out how much sugar is needed for 1 cake.

To find out how much sugar is needed for 1 cake, divide both sides by 5:

5 / 5 = 1

38.5 / 5 = 7.7

Therefore 7.7g of sugar is needed to make 1 cake.

Now times each value by 7 to get the answer :

7.7 x 7 = 53.9g

1 x 7 =  7

Therefore, 53.9g of sugar is needed.

53.9g

Step-by-step explanation:

38.5 / 5 as there are 5 cakes

this will give you the amount of sugar needed for 1 cake, so you X by 7 to find out how many for 7 cakes

38.5 / 5 = 7.7

7.7 X 7 = 53.9g
