Let the number be x.
28% * x = 42
28/100 * x = 42
x = 42 / (28/100)
x = 42*100/28
x = 150

set up the percent as a fraction 28/100. find the equivalent fraction that has a numerator of 42. you need to cross multiply. 28x = 4200
Now divide both sides by 28. Your answer is 150.

28% is 28/100 = 7/25
The number you want is then 42/(7/25) = (42/7)*25 = 6*25 = 150

Set up an equation:
.28x = 42
Now solve for x:
.28x / .28 = 42 / .28
x = 150
