Question

Simonmakes 30 cakes he gives 1/5 of the cakes to Sally he gives 10% of the 30 cakes to Jane what fraction of the 30 cakes does he have left

Answer 1

Answer:

21/30 simplified: 7/10

Step-by-step explanation:

1/5 is equal to 0.20= 20%

10%+20%=30%, so he gave away 30% of his cakes.

30(30%) 0R 30(0.30)= 9

the 9 represents how many cakes he has given away, so you take what he's given away minus the original amount.

30-9=21, he has 21 cakes left

fraction: 21/30 can both be divided by 3--> simplifies to 7/10.
