Answer 2

Answer:

$\frac{-5}{24}$

Step-by-step explanation:

let's use a common denominator! the easiest way is to multiply each side's numerator and denominator by the other's denominator. let's do this problem!

$\frac{-7(8)}{12(8)}$ ----> $\frac{-56}{96}$

$\frac{3(12)}{8(12)}$-----> $\frac{36}{96}$

now that we have similar denominators, we can add the two numerators together!

-56 + 36 = -20!

$\frac{-20}{96}$

but wait! we can simplify it by dividing by 5 on both the numerator and denominator,

$\frac{-5}{24}$
