Question

In May 2017, about 105 devil's lived on Maria island of those, 31% were captured and released into the wild to help struggling populations. How many is that?

Answer 1

Let be "x" the number devils that were captured and released into the wild.

According to the information given in the exercise, about 105 of them lived on Maria Islad. This number is the 100%.

Knowing that 31% were captured and released into the wild, you can set up the following proportion in order to find "x":

`(105)/(100)=(x)/(31)`

Now you must solve for the variable "x" in order to find its value. You get that this is:

`\begin{gathered} (31)((105)/(100))=x \\ \\ (3255)/(100)=x \\ \\ x=32.55 \\ x\approx33 \end{gathered}`

The answer is: About 33 devils were captured and released into the wild.
