Problem 1

Help Sarah find the difference between 3/4 and 1/2.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The difference between the fractions is 1/4.

Explanation

To find the difference, we subtract the fractions: 3/4 - 1/2 = 3/4 - 2/4 = (3-2)/4 = 1/4

Problem 2

What is the result of subtracting 5/6 from 7/8?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The result of the subtraction is 1/24.

Explanation

To find the difference, find a common denominator and subtract: 7/8 - 5/6 = (21/24) - (20/24) = (21-20)/24 = 1/24

Problem 3

Subtract 2/5 from 3/4 and give the result.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The difference is 7/20.

Explanation

Convert fractions to have a common denominator and subtract: 3/4 - 2/5 = 15/20 - 8/20 = (15-8)/20 = 7/20

Problem 4

Find the difference between 9/10 and 3/7.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The difference is 33/70.

Explanation

Find a common denominator and subtract the fractions: 9/10 - 3/7 = 63/70 - 30/70 = (63-30)/70 = 33/70

Problem 5

If John has 5/8 of a pie and eats 1/4 of it, what fraction of the pie is left?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

John has 3/8 of the pie left.

Explanation

Subtract the fraction eaten from the total: 5/8 - 1/4 = 5/8 - 2/8 = (5-2)/8 = 3/8
