"One fifth of a number..."
(1/5)x
"...is added to 1/3 of the same number..."
(1/5)x + (1/3)x
".. If the sum is 96, find the number."
(1/5)x + (1/3)x = 96
You have an equation, so simplify it and solve it from here.

180. I just plugged in numbers to figure it out. I started out with 150 and only got 80, so i knew that the original number had to be larger. So i tried 180 next. You'd take 180 and divide it by 5, which gives you 36. Then you take 180 and divide it by 3, which gives you 60. Add 60 & 36 to get 96.

1/5X+1/3X=96
Multply bothe sides by 15 to get rid of the fractions
3X+5X=1440
combine
8X=1440
divide 1440 by 8
=180

1/5x+1/3x=96
3/13x+5/15x=96
8/15x=96
x=(96*15)/8=180
