Answer 1

To set up the proportion based on the information given, we know that the volume of blood is proportional to body weight.

For the person who weighs 130 pounds and has 4 quarts of blood, we can write:

\[
\frac{4 \text{ quarts}}{130 \text{ pounds}} = \frac{x \text{ quarts}}{150 \text{ pounds}}
\]

Here, \(x\) represents the unknown quantity of blood in quarts for a person who weighs 150 pounds.

So the complete proportion is:

\[
\frac{4}{130} = \frac{x}{150}
\]

This is how you would write the proportion based on the given data.

Therefore, to answer Part 1, you would fill in the blanks as follows:

\[
\frac{4}{130} = \frac{x}{150}
\]
