Question

1. for a 5 in 12 dilution, what is the ratio of serum to saline? what is the ratio of saline to total volume

Explanation:

Step1: Understand the dilution ratio

A 5 in 12 dilution means that there are 5 parts of serum and 12 - 5 = 7 parts of saline.

Step2: Calculate serum - to - saline ratio

The ratio of serum to saline is $\frac{5}{7}$.

Step3: Calculate saline - to - total volume ratio

The total volume is 12 parts. The ratio of saline to total volume is $\frac{7}{12}$.

Answer:

The ratio of serum to saline is $\frac{5}{7}$. The ratio of saline to total volume is $\frac{7}{12}$.
