Question

Mark left 3/8 of pizza in the refrigerator. On friday he ate 1/2 if what is left of the pizza. What fraction of the entire pizza did he eat on friday?

Answer 1

3/16 because 3/8 is equal to 6/16 and half of that is 3/16.

Answer 2

Mike ate
`(3x)/(16)`th portion of the pizza on Friday.

Explanation:

Let us consider the quantity of pizza = x

If Mike left
`(3x)/(8)` of the pizza in the refrigerator.

On Friday he ate
`(1)/(2)` the portion of pizza he ate =
`(3x)/(8)* (1)/(2)`

=
`(3x)/(16)`

Therefore, Mike ate
`(3x)/(16)`th portion of the pizza on Friday.
