18 is what percent of 60?

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

So 18 is x percent of 60

x percent=x/100=
'of' can be translated to as multiply
18=x/100 times 60
18=60x/100

multiply by 10
180=6x
divide by 6
30=x
