Question

In a mixture of concrete, there are two lb of cement mix for each pound of gravel. If the mixture contains a total of 120 lb of these two ingredients, how many pounds of gravel are there?

I suck at word problems.

Answer 1

2lbs of concrete / 1 lb of gravel * 120lbs total.
2 + 1 = 3
120 / 3 = 40
2 * 40 = 80 = concrete
1 *40 = 40 = gravel

Answer 2

sorry, that should say 80 = cement

Answer 3

does this help?

Answer 4
