MyGuruStefan · Answer

Use the following English to algebra translation to write out the requisite equation:

What :  x 
 Percent : ÷ 100
 Is : =
 Greater Than : -

Therefore:  x /100 = (25 - 15)/15

If necessary, cross multiply to solve. Ideally, memorize common fraction to decimal conversions. 10/15 can be reduced to 2/3 and 2/3 = 66.67%.

ScottTargetTestPrep · Answer

We can create the following expression:

(25 - 15)/15 x 100 = 10/15 x 100 = 2/3 x 100 = 66 ⅔%

Alternate Solution:

We see that 25 is 10 more than 15. Thus, 25 is 10/15 greater than 15. We see that 10/15 = 2/3 ≈ 0.67, or 67%

Answer: E
