Answers

8+7+5=20 
220/20=11
8 x 11=88
7 x 11=77
5 x 11=55

Ratio of crushed gravel to water to cement mix = 8:7:5 (for a total of 20 parts)

Thus . .
8/20 = fraction of crushed gravel
7/20 = fraction of water
5/20 = fraction of cement mix

If total is 200 kg, then . . .
(8/20)*(200 kg) =  80 kg crushed gravel
(7/20)*(200 kg) =  70 kg water
(5/20)*(200 kg) =  50 kg cement mix

A) 8 + 7 + 5 = 20 parts
b) 220 kg ÷ 20 = 11
c)  8 parts crushed gravel: 8 x 11 = 88 kg
     7 parts water: 7 x 11 = 77 kg
     5 parts cement: 5 x 11 = 55 kg
