To determine how much of a 125-pound person's body weight is composed of water, we need to calculate 60% of their total weight.
Here is the step-by-step solution:
1. Identify the total body weight:
[tex]\[
\text{Total body weight} = 125 \text{ pounds}
\][/tex]
2. Determine the percentage of the body weight that is water:
[tex]\[
\text{Percentage of water} = 60\% = 0.60
\][/tex]
3. Calculate the water weight:
Multiply the total body weight by the percentage of water:
[tex]\[
\text{Water weight} = 125 \text{ pounds} \times 0.60
\][/tex]
[tex]\[
\text{Water weight} = 75 \text{ pounds}
\][/tex]
So, 60% of a 125-pound person’s body weight, which is composed of water, is exactly 75 pounds.
The correct answer is:
G. 75 pounds
