Question

A bag of flour weighs 5 lb. 5/7 lb of flour was used to make bread. How many

pounds of flour are still in the bag? Give your answer as a mixed number.

Answer 1

Step-by-step explanation:

5/1 - 5/7

35/7 - 5/7

= 30/7 = 4 2/7 lb

Multiply the denominators, 7 by 5,and 1 by 7. When you have the same denominator in each fraction you can subtract. (7x4= 28, 30-28= 2)
