Question

The Graf family made two pizzas. They ate 1 and 1/8 pizza before watching a movie, and 1/2 pizza more after the movie. What is a reasonable estimate for the amount of pizza left

A) Less than 1 1/4
B) More than 1/2
C) Less than 1/3
D) More than 1 1/4

Answer 1

`(3)/(8)` which is less and 1 and 1/4

Explanation:

They have 2 pizzas to start

They ate 1 full pizza and then 1/8 of another. This leaves 7/8 left

They then ate another 1/2 of a pizza. (1/2 also is 4/8)

The Lower common domonitor of the the two is 8. To get 8 from the two you multiply by 4.

So you end up with

`(1)/(2) * 4 = (4)/(8)`

So now you can subtract and get

`(7)/(8) - (4)/(8)`

which the dominator remains the same and you only subtract 7-4 = 3

So your answer is

`(3)/(8)`
