Question

To build the walls of a house, cement and sand are to be mixed in the ratio 1 : 6. How many bowls of sand are to be mixed with three bowls of cement?

Answer 1

Ratio of cement to sand = 1 : 6

∴ Ratio of sand to cement = 6 : 1

Number of bowls of cement = 3

Number of bowls of sand to be mixed = × number of bowls of cement = 6 × 3 = 18

Thus, 18 bowls of sand are to be mixed with 3 bowls of cement to build the wall of a house.
