Solution Steps

Fraction \frac{-5}{2} can be rewritten as -\frac{5}{2} by extracting the negative sign.

$$-\frac{5}{2}-16\left(-5\right)$$

Multiply 16 and -5 to get -80.

$$-\frac{5}{2}-\left(-80\right)$$

The opposite of -80 is 80.

$$-\frac{5}{2}+80$$

Convert 80 to fraction \frac{160}{2}.

$$-\frac{5}{2}+\frac{160}{2}$$

Since -\frac{5}{2} and \frac{160}{2} have the same denominator, add them by adding their numerators.

$$\frac{-5+160}{2}$$

Add -5 and 160 to get 155.

$$\frac{155}{2}$$
