I think it’s -1/20

= -7/20 + -1/20

= -8/20

You divide the denominator by 4 to get 5 since 4 x 5 = 20.

The unknown numerator has to be divided by 4 to get 2. Therefore, 8 divided by 4 is 2.

And the sign will stay the same because they are the same and it’s addition.

-7/20 + -1/20 = -8/20 = -2/5
