Question

$$- \frac { 1 } { 2 } + ( - \frac { 3 } { 4 } )$$

Evaluate

$-\frac{5}{4}=-1.25$

Solution Steps

Least common multiple of $2$ and $4$ is $4$. Convert $-\frac{1}{2}$ and $\frac{3}{4}$ to fractions with denominator $4$.

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

Since $-\frac{2}{4}$ and $\frac{3}{4}$ have the same denominator, subtract them by subtracting their numerators.

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

Subtract $3$ from $-2$ to get $-5$.

$$-\frac{5}{4}$$

Factor

$-\frac{5}{4} = -1\frac{1}{4} = -1.25$
