Question

suppose that an individual has a body fat percentage of 15.4% and weighs 126 pounds. how many pounds of his weight is made up of fat? round your answer to the nearest tenth.

Explanation:

Step1: Identify the formula

To find the amount of fat, we use the formula: Fat weight = Total weight × Body - fat percentage.

Step2: Convert the percentage to a decimal

The body - fat percentage is 15.4%. To use it in the formula, we convert it to a decimal by dividing by 100. So, 15.4% = 0.154.

Step3: Calculate the fat weight

The total weight is 126 pounds. Using the formula Fat weight = 126×0.154.
$126\times0.154 = 19.404$.

Step4: Round to the nearest tenth

Rounding 19.404 to the nearest tenth gives 19.4.

Answer:

19.4 pounds
