There are approximately 4 lbs of muscle for every 5 lbs of body weight of a certain animal. For a 110-lb animal, how much of the weight is muscle?
There are ____ lbs of muscle
A proportion problem where A, B and C are known:
if A : B
then
x? : C
Answer:
x = A*C/B
Now for
4 lbs of muscles : 5 lbs of body weight
x lbs of muscles : 110 lbs of body weight
What is x?
To find out how much of the weight is muscle, we can set up a proportion using the given information.
Let's represent the weight of the animal as "w" and the weight of the muscle as "m".
From the given information, we know that there are approximately 4 lbs of muscle for every 5 lbs of body weight. So, we can write the proportion as:
4 lbs / 5 lbs = m lbs / w lbs
To solve for "m", we can cross-multiply and then divide:
4w = 5m
Divide both sides by 5:
(4w) / 5 = (5m) / 5
Simplifying:
4w / 5 = m
Now we can substitute the given weight of the animal, which is 110 lbs into the equation:
4 * 110 / 5 = m
Solving the equation:
440 / 5 = m
m = 88
Therefore, for a 110-lb animal, approximately 88 lbs of its weight is made up of muscle.
