Question

what should be added to minus 5 by 7 to get minus 2 by 3 minus 2 by 3​

Answer 1

Let the number be x

-5/7 + x = -2/3 - 2/3

-5/7 + x = -4/3

x = -4/3 + 5/7

x = -4(7)/21 + 5(3)/21

x = -28/21 + 15/21

x = -13/21

Therefore -13/21 should be added to -5/7 to get -2/3 -2/3.

Answer 2

The answer is 1 upon 21
