Cement and sand in a ratio 1:3. How much cement is needed for 24 buckets full?
If the ratio of cement to sand is 1:3, it means that for every part of cement, there are 3 parts of sand.
So, the total parts in the mixture would be 1 + 3 = 4.
To find out how much cement is needed for 24 buckets full, we need to divide 24 by the number of parts in the mixture (4), and then multiply the result by the ratio of cement to parts (1):
Cement needed = (24 / 4) x 1 = 6 x 1 = 6
Therefore, 6 buckets of cement are needed for 24 buckets full.
