Question

An adult female elephant weights about 8000 pounds. A newborn baby elephant weights about 200 pounds. Write the ration of the baby elephant’s weight to the adult female elephant’s weight. Write the ratio as a decimal.

Answer 1

For this case, the first thing we must do is define variables.
 We have then:
 w1: weight of baby elephant
 w2: weight of the adult elephant
 We now write the relation of pesos as a fraction:
 $\frac{w1}{w2} = \frac{200}{8000}$
 Simplifying we have:
 $\frac{w1}{w2} = \frac{1}{40}$
 Then, the ratio of weights as a decimal is:
 $\frac{w1}{w2} = 0.025$
 Answer:
 the ration of the baby elephant's weight to the adult female elephant's weight is:
 1:40
 the ratio as a decimal is:
 $\frac{w1}{w2} = 0.025$
