Question

To decrease an amount by 30%, what single multiplier would you use?

Answer 1

You would use 0.7................................

Answer 2

If you want to decrease something by 30%, you multiply the number then subtract the result from the original number. However, you can subtract 30% from 100% then convert to a decimal to get a single multiplier.

100% - 30% = 70%

70% = 0.7

So, 0.7 is the answer.
