Question

You are teaching your class a lesson on subtracting fractions. You assign the problem 9/7 - 5/7. What should the correct answer be?

a) 2/7
b) 4/7
c) -4/7
d) -2/7

Answer 1

To subtract fractions with the same denominator, subtract the numerators and keep the denominator the same. In this case, the answer is 4/7.

Step-by-step explanation:

To subtract fractions, you need to have a common denominator. In this case, both fractions already have the same denominator, which is 7. Subtract the numerators, which gives you 9 - 5 = 4. The denominator remains the same, so the answer is 4/7.
