A person's total body weight is 200 pounds. If their lean body mass is 150 pounds, what is their body fat percentage?

To calculate the body fat percentage, you would subtract the lean body mass from the total body weight to find the body fat weight.

200 pounds - 150 pounds = 50 pounds of body fat

Next, you would divide the body fat weight by the total body weight and multiply by 100 to get the body fat percentage.

(50 pounds / 200 pounds) * 100 = 25%

Therefore, the person's body fat percentage is 25%.
