Answer:

-23/ 84

Step-by-step explanation:

Given:

3/8 + (5/12) + 3/7 + 3/8 + (-5/8) + (-2/7)

solving we get :

3/8 + (5/12) + 3/7 + 3/8 + (-5/8) + (-2/7)

(3/8 -5/8 ) + (3/12 -5/12) + (3/7 - 2/7)

-2/8 + (-2/12) + 1/7

-2/8 - 2/12 + 1/7

-1/4 - 1/6 + 1/7

-21 - 14 + 12 upon 84

-23 / 84

thank you ❤️
