Question

What do I need to multiply by to decrease by 42%?

Answer 1

Hi there!~

So first off we need to use a variable to solve the given percentage, lets use "y" (This can also be used as any other letter, most commonly can be known as "x")

The formula is "$\frac{100-y}{100}$"

And because we are increasing, we would use that ^

So for us we get 0.58 as an answer.
