Question

The sum of two rational numbers is -5 if one of the number is -13/6 find the other number​

Answer 1

Answer: -17/6

======================================================

Work Shown:

• A = first rational number = -13/6
• B = second rational number = unknown

A+B = -5 ... since the sum of both is -5

B = -5-A

B = -5-(-13/6)

B = -5+13/6

B = -30/6 + 13/6

B = (-30+13)/6

B = -17/6 is the answer

Extra info:

This improper fraction converts to the mixed number -2 & 5/6

In decimal form, it's approximately equal to -17/6 = -2.833

Answer 2

`Let \ the \ number \ be = x\\sum \ of \ 2 \ rational \ numbers = -5\\\\x + (-13)/(6) = -5\\\\x - (13)/(6) = -5\\\\`

`x = -5 + (13)/(6) = (-30 + 13)/(6) = -(17)/(6)`

The other rational number = -17/6
