Question 21770: I have three
1. What is 35% of 18
2. What percent of 76 is 15.2
3. 138 is 75% of what number
Answer by wuwei96815(245) (Show Source): 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.
