Question

There are approximately 2lb of muscle for every 51lb of body weight. For a 90 -lb person, approximately how much of the weight is muscle?

Answer 1

3.5294 lb

Step-by-step explanation:

2x90=51xM

180=51M

180/51= 3.5294 lb

Answer 2

To find how much of a 90-lb person's weight is muscle, you multiply the ratio of muscle to body weight (2/51) by the person's total weight, which results in approximately 3.53 lbs of muscle.

Step-by-step explanation:

The question asks us to calculate how much of a 90-lb person's weight is accounted for by muscle, given there are approximately 2 lbs of muscle for every 51 lbs of body weight. To find this, we first need to determine the ratio of muscle mass to total body weight, which is 2/51. Next, we multiply this ratio by the person's total weight:

• Ratio of muscle to body weight = 2/51
• Weight of person = 90 lbs
• Muscle weight = (2/51) × 90 lbs

This calculation will give us the muscle mass for a 90-lb person. Let's do the math:

Muscle weight = (2/51) × 90 lbs ≈ 3.53 lbs

Therefore, approximately 3.53 lbs of a 90-lb person's weight is muscle.
