HELP ME WITH MY HOMEWORK PART 2 :D

(25-15)/25*100%=10/25*100%=40% so 100%-40%=60% 

but more simply                         15 -> 25                 χ=15*100/25 <=>x=1500/25 <=>x=60 so 60% 

                                                    χ ->100             

x% of 25 =15

x=15/25
x=3/5

x=.6

Mulitply by 100 to get percentage

60% of 25=15
