Which number gives you a rational sum when you add it to 4/7
olya-2409 [2.1K]

Answer:

-2/12

Step-by-step explanation:

Given Rational Numbers are 4/7 and 13/7

Adding them we get 4/7+13/7

= (4+13)/7

= 17/7

Therefore, the Sum of 4/7 and 13/7 is 17/7.

Add 5/12 and -3/12?

Given Rational Numbers are 5/12, -3/12

Adding them we get 5/12+(-3)/12

= (5-3)/12

= -2/12
