Final answer:

To find out how much of a 69-lb animal's weight is muscle, we can use the given ratio and set up a proportion. Solving the proportion, we find that 46 lbs of the weight is muscle.


Step-by-step explanation:

To determine how much of the weight of a 69-lb animal is muscle, we can use the given ratio of 2 lbs of muscle to every 3 lbs of body weight. We can set up a proportion:

(2 lbs muscle)/(3 lbs body weight) = (x lbs muscle)/(69 lbs body weight)

Cross multiplying, we get:

2 * 69 = 3 * x

138 = 3x

x = 46

Therefore, 46 lbs of the weight of a 69-lb animal is muscle.
