Question

Find the weight of a person who's body has about 5 quarts of blood

Answer 1

4 quarts of blood are equivalent to 128 pounds.

To find how many pounds are equivalent to 5 quarts, we can use the next proportion:

`\frac{4\text{ quarts of blood}}{5\text{ quarts of blood}}=\frac{128\text{ pounds}}{x\text{ pounds}}`

Solving for x:

`\begin{gathered} 4\cdot x=128\cdot5 \\ x=(640)/(4) \\ x=160\text{ pounds} \end{gathered}`
