If 30 % of ? =17 what is ? i have 2 ways of doing this but i am not sure if either are correct even though both work?
30/100 =17/? i can times both sides by? to get ?x30/100 =17 then x both sides by 100 and divide both sides by 30 to get ?=(17x100)/30 =56.66re.
or can i invert the problem so 100/30 =?/17 then times both sides by 17 to give me 17 x(100/30)=56.66re.
a little guidance would be appreciated
