Question

Subtract and reduce to lowest terms: 4 1/7 - 2 4/7

1. 11/7
2. 2 3/7
3. 1 4/7
4. None of these are correct

Answer 1

Explanation:

Both terms have the same denominator, 7. So combining them is relatively easy. Rewrite 2 4/7 as 18/7 and then subtract 18/7 from 1/7:

1/7 - 18/7 = -17/7

Choose Answer 4: None of these are correct.
