Question

Suppose that an individual has a body fat percentage of 19.2% and weighs 153 pounds. How many pounds of his weight is made up of fat? Round your answer to the nearest tenth.

Answer 1

Step 1

The given body fat percentage = 19.2%

The given body weight = 153 pounds

Required: To find how many pounds of his weight is made up of fat.

Step 2

Find out what 19.2% of his weight is

`\begin{gathered} (100)/(19.2)=(153)/(x) \\ \text{where x represents the value of 19.2\% of his weight in pounds} \end{gathered}`
`\begin{gathered} 100x=\text{ 153}*19.2 \\ (100x)/(100)=(2937.6)/(100) \\ x=29.376\text{ pounds} \\ x\approx\text{ 29.4 pounds to the nearest tenth} \end{gathered}`

Hence, the pounds of his weight made up of fat to the nearest tenth = 29.4 pounds
