Step-by-step explanation:

let unknown no. be x

-6/7 +x = -3/20

x = -3/20 - [-6/7]   here - x - = +

x = -3/20 + 6/7          LCM of 20,7 is 140

x =  [-21 + 120] /140

Answer 2

Step-by-step explanation:

Let the adding number be x

-6/7+x=-3/20

-6/7+3/20=x

-120/140+21/140=x (by making denominator same)

-99/140=x

Hence x=-99/140
