Answer:
17 green frogs
Step-by-step explanation:
You need to multiply the decimal form of 20% by 85.
To find the decimal form of a percent you take the decimal (20.00) and move it twice to the left (20.00 ---> .2000)
Now, multiply by .2 by 85
(.2)(85) = 17
Therefore, 17 frogs in the pond of 85 frogs are green
