Question

$$( - 1.5 - - 21 / 2 + 2 )$$

$11$

The opposite of $-\frac{21}{2}$ is $\frac{21}{2}$.

$$-1.5+\frac{21}{2}+2$$

Convert decimal number $-1.5$ to fraction $-\frac{15}{10}$. Reduce the fraction $-\frac{15}{10}$ to lowest terms by extracting and canceling out $5$.

$$-\frac{3}{2}+\frac{21}{2}+2$$

Since $-\frac{3}{2}$ and $\frac{21}{2}$ have the same denominator, add them by adding their numerators.

$$\frac{-3+21}{2}+2$$

Add $-3$ and $21$ to get $18$.

$$\frac{18}{2}+2$$

Divide $18$ by $2$ to get $9$.

$$9+2$$

Add $9$ and $2$ to get $11$.

$$11$$
