Question

40.5 percent of a certain number is 65. what is the number?

Answer 1

The best way to do this is to set up a proportion

40.5        65
------- = -------
100          x

then cross multiply and divide

100 times 65=6500/40.5=160.5

the number is 160.5

I hope I've helped!

Answer 2

160.49 because you take 65 over x and 40.5 over 100 then cross multiply
