Question

The sum of two rational numbers is 8 If one of the numbers is -5/6 find the other

Answer 1

Let first rational number is x = -5/6
, therefore another number will be (8-x) = 8-(- 5/6) = 8 + 5/6 = (48+5)/6 = 53/6
      

Answer 2

Let the other rational number be x 
 Given One of the numbers is -5/6
          Sum of the two numbers is 8
⇒ x + (-5/6) = 8 
⇒ x - 5/6 = 8 
⇒ x = 8 +5/6
⇒ x = (48+5)/6 = 53/6
Check : x - 5/6 = 8 
          ⇒ 53/6 - 5/6 = 8 
          ⇒ 48/6 = 8 
          ⇒ 8 = 8 
Therefore , L.H.S = R.H.S .
