You can put this solution on YOUR website!
1. 35% of 18 = 35%/100% of 18 = 0.35 of 18 = 0.35(18) = 6.3

2. x% of 76 = 15.2
x% = 15.2/76 = 0.2
x = 0.2 times 100% = 20%

3. 138 = 75% of x = .75x
138/.75 = x
184 = x


I think that the answers are correct, but I am a little bit worried about the notations.
