$$3- \frac{ 1 }{ 2 } -1$$

Evaluate

$$\frac{3}{2}=1.5$$

Solution Steps

$$\frac{5}{2}-1$$

Convert 1 to fraction \frac{2}{2}.

$$\frac{5}{2}-\frac{2}{2}$$

Since \frac{5}{2} and \frac{2}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{5-2}{2}$$

Subtract 2 from 5 to get 3.

$$\frac{3}{2}$$
