A tricky pizza problem requiring multiplication and subtraction of fractions

I have 5/6 of a pizza. If I ate 1/2 of this pizza, How much do I have Left?

Solution

This problem involves multiplying fractions and subtracting fractions.

First, find out how much you ate. Since you ate 1/2 of 5/6, just multiply 1/2 by 5/6

1/2 × 5/6 = (1 × 5)/(2 × 6) = 5/12


Now, you need to subtract 5/12 from 5/6 to find out how much is left after you ate 5/12.


5/6 - 5/12 = (5 × 2)/(6 ×2) - 5/12

5/6 - 5/12 = 10/12 - 5/12

5/6 - 5/12 = (10 - 5)/12

5/6 - 5/12 = 5/12
