Question

80% of the frogs in a pond are spring peepers. If there are 200 frogs in the pond, how many spring peepers are there?

Answer 1

160

Explanation:

If 80% of the frogs in a pond are spring peppers, and there are 200 frogs in the pond, to find how many spring peppers are in the pond, find 80% of 200.

`\begin{aligned} \sf \implies 80\% \textsf{ of }200 & = \sf 80\% * 200\\\\& = \sf (80)/(100) * 200\\\\& = \sf (80)/(100) * (200)/(1)\\\\& = \sf (80 * 200)/(100 * 1)\\\\& = \sf (16000)/(100)\\\\& = \sf 160\end{aligned}`

Therefore, there are 160 spring peppers in the pond.
