Question

In a concrete mixture, the ratio of cement to sand is 1 to 4. At this ratio, how many shovelfuls of cement would be needed to be mixed with 80 shovelfuls of sand?

Answer 1

Answer: 20 shovelfuls of cement would be needed to be mixed with 80 shovelfuls of sand.

Explanation:

First, we'd find out 4 divided by 1. This would equal 4.

Because we knew the amount of sand we had, we'd divide instead.

80 divided by 4

(If we had known the amount of cement we had, we would multiply)

This equals 20. This is how we get our answer, 20 to 80
