Question

simon makes 30 cakes gives 1/5 of the cakes to sali. He gives 10% of the 30 cakes to jane what fraction of the fake cakes does he have left

Answer 1

Total number of cakes made by Simon = 30 cakes.

Number of cakes gave to Sali = 1/5 Of total cakes = 1/5 * 30 = 6 cakes.

Number of the cakes gave to Jane = 10% of 30 cakes

10% can be written as 10/100 in fracions and in decimals it would be 0.10.

Therefore, 10% of 30 cakes = 0.10 times 30 = 3 cakes.

Total number of cakes left = Total cakes made - Cakes gave to Sali - Cakes gave to Jane = 30-6-3

Therefore, Total number of cakes left = 21.

21 cakes left our of 30 cakes.

21 out of 30 could be written in fracion form as 21/30.

We can reduce this fracion in simplest form by dividing top and bottom by 3, we get

7/10.

Therefore, 7/10 fraction of the cakes does he have left.
