Sasha bought a pizza that was cut into 12 pieces. She ate 1/4 of the pizza after school. Her brother Eli ate 1/3 of the pizza after soccer practice. What fraction of the original pizza was left for their dad to eat?
A) l/2
B) 2/3
C) 5/12
D) 10/12

A) 1/2

Step-by-step explanation:

1/4 of 12 is 3

==> (1/4) * 12 = 3

12-3=9

Meaning what's 1/3 of 9? Which is also 3 because 3+3+3= 9 but only ate ONE of those three 3's. Giving us 6 more slices left.

6 is half of 12 because 6/12 is simplified to 1/2

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
