The number of buckets of gravel that are needed for 4 buckets of cement is 24 buckets of gravel
If concrete tiles are made using buckets of cement, sand, and gravel mixed in the ratio 1:4:6, this shows that the ratio of the cement to gravel is 1: 6
1 cement = 6 portion of gravel
If there are 4 buckets of cement, then;
4 bucket of cement = x
Cross multiply
1 * x = 4 * 6
x = 4 * 6
x = 24
Hence the number of buckets of gravel that are needed for 4 buckets of cement is 24 buckets of gravel
