Final answer:
To calculate the weight of body fat, convert the weight from pounds to kilograms and multiply it by the body fat percentage.
Step-by-step explanation:
To calculate the weight of body fat, we can use the given body fat percentage and weight. First, we convert the weight from pounds to kilograms. Since 1 pound is approximately equal to 0.45 kilograms, the weight in kilograms is 139 pounds x 0.45 = 62.55 kilograms.
Next, we calculate the weight of body fat by multiplying the weight in kilograms by the body fat percentage. 62.55 kilograms x 0.185 = 11.55 kilograms of body fat.
Therefore, approximately 11.55 pounds of her weight is made up of body fat.
