$$\frac{91}{2}-\frac{3}{4}$$

Least common multiple of 2 and 4 is 4. Convert \frac{91}{2} and \frac{3}{4} to fractions with denominator 4.

$$\frac{182}{4}-\frac{3}{4}$$

Since \frac{182}{4} and \frac{3}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{182-3}{4}$$

Subtract 3 from 182 to get 179.

$$\frac{179}{4}$$

Factor

$$\frac{179}{2 ^ {2}} = 44\frac{3}{4} = 44.75$$
