Answer 1

Hey mate

-3/8 + 18/8 = 15/8.

Answer 2

$\sf\underline{Step-by-step \: explanation}$

Let the faction be x

$\frac{ - 3}{8} \: + \: x \: = \frac{15}{12}$

$x \: = \: \frac{15}{12} \: - \: \frac{ - 3}{8}$

Lcm of 12 and 8 = 24


$\dfrac{-3}{8}$ = $\dfrac{-9}{24}$


$\dfrac{15}{12}$ = $\dfrac{30}{24}$



$\dfrac{30}{24}$ - $\dfrac{-9}{24}$

$x \: = \: \frac{39}{24}$
