Question

Write your answer as a fraction or as a whole or mixed number.

pounds

Answer 1

The chemistry textbook weighs 2 3/4 pounds.

The geometry textbook weighs 5/8 of a pound.

To find the difference, we need to subtract the weight of the geometry textbook from the weight of the chemistry textbook.

2 3/4 - 5/8 = (11/4) - (5/8)

Convert 11/4 into a fraction with a common denominator of 8.

11/4 = 22/8

Now subtract:

22/8 - 5/8 = 17/8

So, the chemistry textbook weighs 17/8 pounds more than the geometry textbook.
