Question

$$- \frac { 7 } { 2 } - 3 - 4$$

Evaluate

$-\frac{21}{2}=-10.5$

Solution Steps

Convert $3$ to fraction $\frac{6}{2}$.

$$-\frac{7}{2}-\frac{6}{2}-4$$

Since $-\frac{7}{2}$ and $\frac{6}{2}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{-7-6}{2}-4$$

Subtract $6$ from $-7$ to get $-13$.

$$-\frac{13}{2}-4$$

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

$$-\frac{13}{2}-\frac{8}{2}$$

Since $-\frac{13}{2}$ and $\frac{8}{2}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{-13-8}{2}$$

Subtract $8$ from $-13$ to get $-21$.

$$-\frac{21}{2}$$

Factor

$-\frac{21}{2} = -10\frac{1}{2} = -10.5$
