in a mixture of water and 1/4 is sand.write down the ratio of water to sand
In a full cup you have
1/4 sand
and
3/4 water
so
water/sand = 3/4 / 1/4 = 3/1 = 3
To determine the ratio of water to sand in the mixture, we need to compare the amount of water to the amount of sand.
Let's assume we have 1 unit of the mixture (e.g., 1 liter, 1 kilogram, etc.).
Given that 1/4 of the mixture is sand, this means that the sand constitutes 1/4 of the total mixture. Therefore, the water must make up the remaining 3/4 of the mixture.
So, for every 3 parts of water, there is 1 part of sand.
Thus, the ratio of water to sand in the mixture is 3:1.
