Question

Thirty-six percent of what number is 180?
(Points : 4)
500
515
540
550

Answer 1

Well, to start, how do you write 36 percent as a decimal?

Answer 2

you could do cross multiplication so...
36/100 = x/180
Thats how you would start out ...
That would be equal to 36x=100(180)
Which is simplified to 36x=18000
You would then divide by 36 on BOTH sides of the equation.
It would equal 500!
So 36% of 500 = 180 :D
