I'm not sure but I think I may have the answer to number 9
It says she uses 3 draws for shirts and wants to find out the percentage. Percentage is normally out of 100% so we do 100÷4 (we divide by 4 because there are 4 drawers)
100÷4=25. So now it says she uses three drawers for her shirts so we need to do 25x3=75 and all you do with that is put it in percent. The answer is 75%
P.S I am not entirely sure that this is correct but I wanted to help ❤
