In a mixture of concrete, there are three lb of cementt mix for each pound of gravel if the mixture contains a total of 208 lb of these two ingredients how many pounds of GRAVEL are there.
3 parts cement to 1 part gravel = 4 equal parts
1/4 * 208 = 52 lbs of gravel
I'm rounding but I think your answer is 70 lb of gravel.
I'm not sure if this is the right answer so I would wait for another answer to be sure.
