Question 21770
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.
