Francisco had 2 1/2 pizzas left over after his birthday party. The next day he and his family ate 1 1/4 of the left over pizza. How much of the pizza is now left over?

Question

Which operation(s) will you use for the problem?

Answer 1

Reread the problem identifying the total as 2 and 1/2 and the part as 1 and 1/4. When the family ate 1 and 1/4 pizza, it was subtracted from the total. The equation would be total minus part:

2 1/2 — 1 1/4 =

Now the equation can be solved, set up our problem vertically, lining up our whole numbers and fractions. It is important to remember: when adding and subtracting fractions, we need a common denominator. The fraction 1/2 can be multiplied by 2 to create the equivalent fraction 2/4.

The new problem is 2 and 2/4 minus 1 and 1/4. Now, 1/4 can be subtracted from 2/4, which equals 1/4. Whole numbers 2-1=1. The answer is the mixed number 1 and 1/4.

Answer 2

Actual answer: None. I et the rest of it.

The answer the question wants:

2 and 1/2 - 1 and 1/4 = 5/2 - 5/4 = 10/4 - 5/4 = 5/4 = 1 and 1/4

Answer 3

Answer 4

First I would break the fractions apart into the sum of a whole number and a fraction (which is the Associative Property of Addition). Then I would use the Distributive Property of Equality to distribute the "-" (aka, "-1) to the "1" and the "1/4). Then I would use the Commutative Property of Equality to regroup the two integers together and the two fractions together. Then I would get a common denominator for the "1/2" by multiplying it by "2/2" which is the Identity Property of Multiplication.

The actual "operations" are addition, subtraction, and multiplication.
