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

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 ""

And because we are increasing, we would use that ^

So for us we get 0.58 as an answer. 

Why you be expecting me to do your math u stupid butt? i ain't gonna but ima get points so you know what i'm sayin boii
