Answer 1

e) $\frac{8}{-15} + \frac{-1}{15}$

Now as the the negative sign is in the denominator of the first rational number (8/-15). V can take the negative sign on the numerator. $\frac{-1}{1} = \frac{1}{-1}$

= $\frac{-8}{15} + \frac{-1}{15}$

As the denominators r same, it is easy to solve.

$\frac{-8 + (-1)}{15} = \frac{-9}{15}$  (Negative + Negative = Positive)

As 9 and 15 r both divisible by 3, v can reduce it to its simplest form.

$\frac{-9}{15} = \frac{-3}{5}$

Final answer:

$\frac{8}{-15} + \frac{-1}{15} = \frac{-3}{5}$
