Alright so I thought of it like this. 30 is 30% of 100 divide 30 in 1/2 you get 15. divide 100 in half to make it proportional. And you get 50. But another more mathematical way is as follows So you have your 15 Then you convert your percent into a decimal. 30% converts to 0.30 Divide your 15 by the converted percentage...so ex: 15/0.3 calculate and it should equal 50. So 15 is 30% of 50
