To decrease an amount by 18%, what single multiplier would you use?

I believe you would calculate this like so;

We want 18% less than 100% of that amount therefore the single multiplier we would use is as follows:

(100% - 18%) = 82%

Which alternatively = 0.82

Does that make sense? If not I can explain it a bit more. Please let me know.

Answer:

0.82

Explanation:

We are asked to find the single multiplier used to show an amount decreased by 18%.

Since amount is decreasing by 18%, this means that 82% (100-18) of the amount is remaining.

The multiplier will be in decimal form, so we will convert 82% to decimal as:


(82)/(100)=0.82

Therefore, our required single multiplier is 0.82.
