Question

1. for a 4 in 15 dilution, what is the ratio of urine to water? what is the ratio of water to total volume?

Explanation:

Step1: Understand the dilution ratio

A 4 in 15 dilution means that there are 4 parts of urine and 15 - 4 = 11 parts of water.

Step2: Calculate urine - to - water ratio

The ratio of urine to water is $\frac{4}{11}$.

Step3: Calculate water - to - total volume ratio

The total volume is 15 parts. The ratio of water to total volume is $\frac{11}{15}$.

Answer:

The ratio of urine to water is $\frac{4}{11}$. The ratio of water to total volume is $\frac{11}{15}$.
