$$D=2.5-( \frac{ -1 }{ 5 } )$$

$D=2.7$

Fraction $\frac{-1}{5}$ can be rewritten as $-\frac{1}{5}$ by extracting the negative sign.

$$D=2.5-\left(-\frac{1}{5}\right)$$

The opposite of $-\frac{1}{5}$ is $\frac{1}{5}$.

$$D=2.5+\frac{1}{5}$$

Convert decimal number $2.5$ to fraction $\frac{25}{10}$. Reduce the fraction $\frac{25}{10}$ to lowest terms by extracting and canceling out $5$.

$$D=\frac{5}{2}+\frac{1}{5}$$

Least common multiple of $2$ and $5$ is $10$. Convert $\frac{5}{2}$ and $\frac{1}{5}$ to fractions with denominator $10$.

$$D=\frac{25}{10}+\frac{2}{10}$$

Since $\frac{25}{10}$ and $\frac{2}{10}$ have the same denominator, add them by adding their numerators.

$$D=\frac{25+2}{10}$$

Add $25$ and $2$ to get $27$.

$$D=\frac{27}{10}$$

$D≔2.7$
