To find the difference in weight between the chemistry and geometry textbook, subtract the weight of the geometry textbook from the weight of the chemistry textbook.
Weight of Chemistry textbook: 9 1/4 pounds
Weight of Geometry textbook: 7 2/3 pounds
9 1/4 pounds - 7 2/3 pounds = (36/4 + 1/4) pounds - (22/3 + 2/3) pounds
= 37/4 pounds - 26/3 pounds
To simplify this, find a common denominator for both fractions, which is 12.
37/4 pounds = (37/4)(3/3) pounds = 111/12 pounds
26/3 pounds = (26/3)(4/4) pounds = 104/12 pounds
Now subtract the weights:
111/12 pounds - 104/12 pounds = (111 - 104)/12 pounds = 7/12 pounds
Therefore, the chemistry textbook weighs 7/12 pounds more than the geometry textbook.
Philip's chemistry textbook weighs 9 1/4 pounds and his geometry textbook weighs 7 2/3 pounds. How much more does the chemistry textbook weigh than the geometry textbook?
