Adding & Subtracting Fractions
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
59 + 39 = 818.
Rewrite: 59 + 39 = 89 because you add the numerators and the denominator stays 9.
2. Fix the sentence:
67 − 37 = 30.
Rewrite: 67 − 37 = 37 because you subtract only the numerators and keep the denominator 7.
3. Fix the sentence:
210 + 610 = 820.
Rewrite: 210 + 610 = 810 because like fractions share the same denominator, so it does not change.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 15 + 35 = 45.
2. 1012 − 712 = 312.
3. 311 + 511 = 811.
4. 89 − 69 = 29.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. What is 610 + 410? Can the answer be written as a whole number?
610 + 410 = 1010, which equals 1 whole. Whenever the numerator and denominator are the same, the fraction equals 1.
2. A pizza is cut into 8 equal slices. You eat 38 and your friend eats 28. How much is left?
First add the eaten slices: 38 + 28 = 58. Then subtract from the whole: 88 − 58 = 38. There are 38 of the pizza left.
Adding & Subtracting Fractions
★ Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1) Fix the sentence:
5/9 + 3/9 = 8/18.
Rewrite: 5/9 + 3/9 = 8/9 because you add the numerators and the denominator stays 9.
2) Fix the sentence:
6/7 − 3/7 = 3/0.
Rewrite: 6/7 − 3/7 = 3/7 because you subtract only the numerators and keep the denominator 7.
3) Fix the sentence:
2/10 + 6/10 = 8/20.
Rewrite: 2/10 + 6/10 = 8/10 because like fractions share the same denominator, so it does not change.
★ Part B: Fill in the Blank
Write the missing word or number on each line.
1) 1/5 + 3/5 = 4/5.
2) 10/12 − 7/12 = 3/12.
3) 3/11 + 5/11 = 8/11.
4) 8/9 − 6/9 = 2/9.
★ Part C: Short Answer
Answer each question in one or two complete sentences.
1) What is 6/10 + 4/10? Can the answer be written as a whole number?
6/10 + 4/10 = 10/10, which equals 1 whole. Whenever the numerator and denominator are the same, the fraction equals 1.
2) A pizza is cut into 8 equal slices. You eat 3/8 and your friend eats 2/8. How much is left?
First add the eaten slices: 3/8 + 2/8 = 5/8. Then subtract from the whole: 8/8 − 5/8 = 3/8. There are 3/8 of the pizza left.
