Please help! work it all out please!

Answer 1

I think the percentage decrease would be 20%

Answer 2

I'll be helping you with the first question. :)

First, we want to write this as a fraction.

18/15 = 1 3/15.

One and three fifteenths is equal to 1 1/5, which is 120% as a percentage. Therefore, the percent increase is 20%.

Hope this helped ^^
