first you set up a proportion 18 over ? = 60 over 100 then cross multiply. 18*100=1800 then divide that by 60 and you get 30 or 18/60=x 0.30=x 30 hope this helps!!!!
so 18 is x percent of 60 perctn means parts out of 100 so x percent=x/100= 'of' can be translated to as multiply 18=x/100 times 60 18=60x/100 18=6x/10 multiply by 10 180=6x divide by 6 30=x the answer is 30%
