Belle's chemistry textbook weighs 2 3/4 pounds and her geometry textbook weighs 5/8 of a pound. How much more does the chemistry textbook weigh than the geometry textbook?
Write your answer as a fraction or as a whole or mixed number.
pounds
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.
