Question

What is the decimal multiplier to decrease by 3.9%?

Answer 1

To decrease a number by 3.9 percent, the number must be multiplied by 0.961.

Step-by-step explanation:

The decimal multiplier to decrease any number by 3.9% will be the number in decimal form which when multiplied with the number will yield a number that is 3.9% smaller than the number itself.

Let's consider an example to illustrate this.

4 to decrease by 3.9% = 4 - (4 * 3.9/100) = 4 - 0.156 = 3.844

Now the above answer 3.844 can be directly gotten by multiply 4 with 0.961 which is the decimal version of (1 - 3.9/100) = 1 - 0.039 = 0.961

4 * 0.961 = 3.844

So 0.961 is the decimal multiplier to decrease by 3.9%.
