Let the number be n:

n -  \frac{3}{4} n = 28

LCD (Least Common Denominator) is 4.  Multiply each term by 4, simplify each term, if needed. Then solve for n.

(4)n - 4( \frac{3}{4}n)= (4)(28)

4n - 3n = 112

n = 112.

The number is 112.

To check:
112- ( \frac{3}{4})(112) = 28

112 - 84 = 28
28 = 28
