Question

8/-5. + -1/2 how do you do it because I really don't know

Answer 1

$\implies {\blue {\boxed {\boxed {\purple {\sf { \frac{ - 21}{10} \:(or) \: - 2 \frac{1}{10} }}}}}}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

$\frac{8}{ - 5} + ( \frac{ - 1}{2} )$

$\\= \frac{ - 8}{5} - \frac{1}{2}$

Since the denominators are unequal, we find the L.C.M (lowest common multiple) for both denominators.

The L. C. M for 5 and 2 is 10.

Now, multiply the L.C.M. with both numerator & denominator.

$\\ = \frac{ - 8 \times 2}{5 \times 2} - \frac{1 \times 5}{2 \times 5}$

$\\= \frac{ - 16}{10} - \frac{5}{10}$

Now that the denominators are equal, we can subtract the numerators.

$\\= \frac{ - 16 - 5}{10}$

$\\= \frac{ - 21}{10}$

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