Al, Barb, and Calvin shared a large pepperoni pizza after school. Al ate 1/3 of the pizza, Barb ate 1/4 of the pizza. and Calvin ate the rest. What is the ratio of Al's share of the pizza, to Barb's share, to Calvin's share? a. 4:3:5

b. 3:4:7

c. 5:4:3

d. 3:4:5

e. 4:5:7

A: 4:3:5

Step-by-step explanation:

Al ate 1/3 of the pizza. 1/3 can also be written as 4/12. Barb ate 1/4 of the pizza. 1/4 can also be written as 3/12. 4/12 plus 3/12 is equal to 7/12. One whole would be 12/12, so to get the remaining amount of pizza, do 12/12-7/12, to give you 5/12. 4:3:5. We needed to make all of the fractions have a common denominator in order to solve this particular problem.

a² + b²= c²

24² + 7² = c²

c= 25

g
