Question

Dry concrete can be made by mixing sand gravel and cement. The ratio of 1:2:4 if you want 14,000 kg of dry concrete how much would you need?

Answer 1

2,000kg X 1 = 2,000kg

2,000kg X 2 = 4,000kg

2,000kg X 4 = 8,000kg

Answer 2

Explanation:

Add up 1,2,4 which is 7. Then do 14,000/7 which gives you 2,000kg. Then multiply the 2,000kg with each number in the ratio. It can be tricky to grasp this method at first, but believe me when I say that after practice it becomes almost second nature.

Answer:

2,000kg X 1 = 2,000kg

2,000kg X 2 = 4,000kg

2,000kg X 4 = 8,000kg
