Question

$237.51 is 20% of what number

Answer 1

They're basically asking 

 

237.51 = .20 * X

 

Dividing both sides by .20 gives

 

X = 237.51 / .20

 

The final step is simple math

Answer 2

Whenever you see the words "what number" in a word problem, replace it with "x".  In this problem, that would change the problem into "$237.51 is 20% of x", which written as an equation, would get you:

 

$237.51 = 0.20 * x

 

Solve for x.
