Explanation
70 L of milk and water
56 L of pure milk
70-56 = 14 L of water
To form the ratio of milk to water, we write the corresponding values for each separated by a colon.
We get the ratio 56:14 which fully reduces to 4:1
Divide each part by the GCF 14 to reduce the ratio. Think of the ratio as a fraction. Meaning that 56/14 = 4/1.
A ratio of 4:1 means there's 4 times as much milk compared to water.
The order is very important since 1:4 is incorrect. We list the milk part first since "ratio of milk to water" mentioned milk first.
