Question

The sum of two rational numbers is-7/13. If one of the numbers is-5/39, find the other number​

Answer 1

Answer:

-7/13-(-5/39) (sign will change)

-7/13+5/39 (lcm of 13 and 39)

-21+5/39

-16/39 (sign of bigger number)

-16/39 is the answer

Answer 2

Answer: -16/39

Step-by-step explanation:

Let one rational number be = x (-5/39)

second rational number be = y

x + y = -7/13 (given)

-5/39 + y =-7/13

y = -7/13 + 5/39

y = -21 +5/39

y = -16 /39
