What is ... 30% of ... is 60?

So question is 'what is x. 30% of x is 60'

remember that percent means parts out of 100 so therefor

30%=30/100=3/10

so the question is

3/10 of x is 60

'of' in math means multiply

3/10 times x=60

3x/10=60

mulitply both sides by 10 to get rid of fraction

3x=600

divide both sides by 3

x=200

... is 200

the number is 200
