Question

To increase an amount by 24% what single multiplier would you use?

Answer 1

Let x be the original amount.

Increasing x by 24% means to add 24% of x to the original amount x.

x + 24% of x = x + .24x = 1x + .24x = 1.24x.

Therefore, to increase a given amount by 24% then multiply the original amount by a single factor of 1.24 .

Answer 2

If you are increasing an amount in percentage, here's a trick, you simply add 100% to it.

That is 100% + 24% = 124%.

Therefore the single multiplier = 124% = 124/100 = 1.24.

If you were decreasing in percentage, here's a trick, you simply subtract it from 100% to it.

That is 100% - 24% = 76.

Therefore the single multiplier = 76% = 76/100 = 0.76.
