If ⅜ of a 60-pound bag of ready-mix concrete is Portland cement, how many pounds of other materials are in the bag?

(3/8) * 60 = 180/8 = 22 1/2

60 - 22 1/2 = ?

To find out how many pounds of other materials are in the bag, we need to subtract the weight of the Portland cement from the total weight of the bag.

First, we need to determine the weight of the Portland cement. Given that 3/8 of the bag is Portland cement, we can calculate it by multiplying 3/8 by the total weight of the bag.

Weight of Portland cement = (3/8) * 60 pounds

To solve this, we can simplify the fraction by dividing the numerator (3) by the denominator (8), resulting in 0.375.

Weight of Portland cement = 0.375 * 60 pounds

Multiplying these values together, we get:

Weight of Portland cement = 22.5 pounds

Since Portland cement weighs 22.5 pounds, we can find the weight of the other materials by subtracting this amount from the total weight of the bag.

Weight of other materials = Total weight of the bag - Weight of Portland cement

Weight of other materials = 60 pounds - 22.5 pounds

Subtracting the values, we get:

Weight of other materials = 37.5 pounds

Therefore, there are 37.5 pounds of other materials in the bag.
