There are approximately 4 lbsof muscle for every 5 lbs of body weight of a certain animal. For a 125-lb animal, how much of the weight is muscle

To determine how much of the weight is muscle, we can use the given ratio of 4 lbs of muscle for every 5 lbs of body weight.

1. Calculate the fraction of the weight that is muscle: 4 lbs / (4 lbs + 5 lbs) = 4 lbs / 9 lbs.

2. Multiply the fraction by the weight of the animal: 4 lbs / 9 lbs x 125 lbs = 55.56 lbs.

Therefore, approximately 55.56 lbs of the 125-lb animal's weight is muscle.

To find out how much of the weight is muscle for a certain animal, we need to calculate the ratio of muscle weight to body weight and then multiply it by the body weight.

Given that there are approximately 4 lbs of muscle for every 5 lbs of body weight, we can represent this as a ratio: 4 lbs muscle : 5 lbs body weight.

Now, let's calculate the amount of muscle for a 125-lb animal.

Step 1: Calculate the ratio
Since the ratio is 4 lbs muscle : 5 lbs body weight, we can calculate the muscle weight as a fraction of the body weight: 4/5.

Step 2: Calculate the muscle weight
To find out the muscle weight, we multiply the body weight by the ratio we calculated: (4/5) * 125 lbs.

Calculating this expression: (4/5) * 125 lbs = 100 lbs.

Therefore, for a 125-lb animal, approximately 100 lbs of the weight is muscle.

Let's use a proportion. Cross multiply and solve for x.

4/5 = x/125
