Solve 9/4-2+1/2

$$\frac { 9 } { 4 } - 2 + \frac { 1 } { 2 }$$

Evaluate

$$\frac{3}{4}=0.75$$

Solution Steps

Convert 2 to fraction \frac{8}{4}.

$$\frac{9}{4}-\frac{8}{4}+\frac{1}{2}$$

Since \frac{9}{4} and \frac{8}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{9-8}{4}+\frac{1}{2}$$

Subtract 8 from 9 to get 1.

$$\frac{1}{4}+\frac{1}{2}$$

Least common multiple of 4 and 2 is 4. Convert \frac{1}{4} and \frac{1}{2} to fractions with denominator 4.

$$\frac{1}{4}+\frac{2}{4}$$

Since \frac{1}{4} and \frac{2}{4} have the same denominator, add them by adding their numerators.

$$\frac{1+2}{4}$$

Add 1 and 2 to get 3.

$$\frac{3}{4}$$

Factor

$$\frac{3}{2 ^ {2}} = 0.75$$
