materials are in the bag? Show work and express as mixed number. Show work.
A. 36 5/8
B. 36 1/2
C.37 3/4
D. 37 1/2

Answer 1

To find the weight of the other materials in the bag, subtract the weight of the Portland cement from the total weight of the bag. The weight of the other materials is 37 1/2 pounds.

Step-by-step explanation:

To find the weight of the other materials in the bag, we need to subtract the weight of the Portland cement from the total weight of the bag. Since 3/8 of the bag is Portland cement, 5/8 of the bag is the weight of the other materials.

First, find the weight of the Portland cement by multiplying 3/8 by 60 pounds:

(3/8) * 60 = 22.5 pounds

Next, subtract the weight of the Portland cement from the total weight of the bag:

60 pounds - 22.5 pounds = 37.5 pounds

Since 37.5 pounds can be expressed as a mixed number, the answer is 37 1/2 pounds.
