Question

what is 150% of 18 ?

Answer 1

18/x=100/150
(18/x)*x=(100/150)*x       - we multiply both sides of the equation by x
18=0.666666666667*x       - we divide both sides of the equation by (0.666666666667) to get x
18/0.666666666667=x 
27=x 
x=27

now we have: 
150% of 18=27

 

Answer 2

100%=18
50% is 18/2=9 so 50%=9
18+9=27
So 150% of 18 is 27

Hope this helps!! :D
