Math worksheet for subtracting fractions with like denominators using circle models.

Let’s solve each problem one by one. We’re subtracting fractions with the same denominator — that means we just subtract the top numbers (numerators) and keep the bottom number (denominator) the same.

Problem 2:

Newton has ⁴₆ of the pizza.
He eats ¹⁄₆.
What fraction is left?

We do:
⁴⁄ – ¹⁄₆ = (4 - 1)/6 = ³⁄₆

So, the answer is 3 over 6.

Fraction sentence:
⁴⁄ – ¹⁄₆ = ³⁄₆

Problem 3:

Sally has ⁴⁄₅ of the pizza.
She eats ³⁄₅.
What fraction is left?

We do:
⁴⁄ – ³⁄₅ = (4 - 3)/5 = ¹⁄₅

So, the answer is 1 over 5.

Fraction sentence:
⁴⁄₅ – ³⁄₅ = ¹⁄₅

Problem 4:

Flame has ⁵⁄₇ of the pizza.
She eats ³⁄₇.
What fraction is left?

We do:
⁵⁄ – ³⁄₇ = (5 - 3)/7 = ²⁄₇

So, the answer is 2 over 7.

Fraction sentence:
⁵⁄₇ – ³⁄₇ = ²⁄₇

Problem 5:

Frazer has ⁷⁄₈ of the pizza.
He eats ⁴⁄₈.
What fraction is left?

We do:
⁷⁄₈ – ⁴⁄₈ = (7 - 4)/8 = ³⁄₈

So, the answer is 3 over 8.

Fraction sentence:
⁷⁄₈ – ⁴⁄₈ = ³⁄₈

Final Answer:

2) ³⁄₆ → Fill in: 3

3) ¹⁄₅ → Fill in: 1, and fraction sentence: 4/5 - 3/5 = 1/5

4) ²⁄₇ → Fill in: 2, and fraction sentence: 5/7 - 3/7 = 2/7

5) ³⁄₈ → Fill in: 3, and fraction sentence: 7/8 - 4/8 = 3/8
