Question

Sam makes 60 cakes. He gave 20 percent of the cakes to Sarah. he gave 1 sixth of the 60 cakes to lily. What fraction of the 60 cakes does he have left

Answer 1

he has (38/60) cakes left. simplified it is (19/30)

Explanation:

1. 60 cakes *
`(20)/(100)`=60*(2/10) or (1/5)

we come to 60 *
`(1)/(5)`=12 cakes

2. 1/6 of the cakes equals 10 because if you divide 60 by 6, you get 10.

3. add 10+12 to get 22 cakes that Sam has given away.

4. subtract 22 cakes from the original 60 to get 38 cakes left over.

5. Sam has 38/60 cakes left and simplified it is (19/30)
