To decrease an amount by 31 percent multiply by?

Answer 1

Short answer: 0.69

Take 100. 31% = 31, 100-31=69

Of course, when you increase the result by 31 percent you do not get the 100 back. But that was not the question.

But, for completeness what do I multiply by to get the number, when adding 31 percent, gives me the original number, it is 0.7633 (1/1.31)

Answer 2

0.69?
