I.e., what must x be if x% of 10 is 20?

OpenStudy (anonymous):

would it be 2

OpenStudy (jamesj):

No, not 2%. 2% of 10 is just 0.2

OpenStudy (anonymous):

oh ok

OpenStudy (jamesj):

200% of 10 is 20.

OpenStudy (anonymous):

oh ok

OpenStudy (anonymous):

50% of what number is 10 ? .5 of what number is 10 ? .5 x = 10 x = 10/.5 x = 20

OpenStudy (jamesj):

robtobey is right. I misread the question. 50% of x is 10. What must that number x be. I.e., what number when halved is 10? That number is 20.
