Answer 1

Answer:

-23/24

Step-by-step explanation:

(-3/8)+(-7/12)

-3/8-7/12

(-9-14)/24

-23/24

Answer 2

Step-by-step explanation:

Here the denominators are different. So we make them the same by finding the LCM of 8 and 12, which is 96

= -3×12/8×12 + -7×8/12×8

= -36/96 + -56/96

= - (-36)+(-56)/96

=-92/96 (cancelled numerator and denominator)

= -46/48 (cancelled numerator and denominator)

= -23/24
