Question
A pizza is cut into 12 slices. Mark eats 1/4 of the pizza, Sarah eats 1/3, and John eats the rest. How many slices did John eat?
Options
- A. 3
- B. 4
- C. 5
- D. 6
- E. 2
Correct answer
C. 5
Explanation
There are 12 slices altogether. Mark eats 1/4 of the pizza: 1/4 x 12 = 3 slices Sarah eats 1/3 of the pizza: 1/3 x 12 = 4 slices Together they eat: 3 + 4 = 7 slices So John gets the rest: 12 - 7 = 5 slices So John gets 5 slices.
