Question

There were 60 ducks living in a pond. If the number living at the pond increased by 30%, how many ducks now live at the pond?

Answer 1

78

Explanation:

You take the original total: 60, and multiply it by 30 to get 1,800. You then divide 1,800 by 100 to get 18. 18 is your 30%. Now, you add the 30% to 60 getting your total number of ducks: 78.

The equation version:

`(a)/(60) = (30)/(100)`

It is just proportions.
