Question

the volume of blood in a persons body is proportional to body weight. a person who weighs 170 pounds has approximately 5 quarts of blood. estimate the number of quarts of blood in a person who weighs 150 pounds.

complete the proportion, where the ratios have volumes of blood in the numerators and body - weights in the denominators.

\\(\frac{x}{\square}=\frac{\square}{\square}\\) (do not simplify)

Explanation:

Step1: Set up the proportion

Since the volume of blood is proportional to body - weight, if we let $x$ be the number of quarts of blood in a 150 - pound person, the proportion is $\frac{x}{150}=\frac{5}{170}$.

Answer:

$\frac{x}{150}=\frac{5}{170}$
