Question

the sum of two rational numbers is 8 .if one of the number is -5/6 find the other

Answer 1

Let the no. be x
x+(-5/6)=8
x-5/6=8
6x-5/6 = 8
6x - 5= 8x6
6x = 48+5
6x = 53
x= 53/6   Ans.

Answer 2

Given,

The sum of two rational numbers = 8.

One of the numbers is -5/6.

To Find,

The other number =?

Solution,

We can solve the question using the following steps:

It is given that one of the numbers is -5/6.
Let, the other number = $x$

The sum of the two numbers is equal to 8. In equation form,

$x + (- \frac{5}{6} ) = 8$

$x - \frac{5}{6} = 8$

$x = 8 + \frac{5}{6}$

$x = \frac{53}{6}$

Therefore,

$\frac{-5}{6} + \frac{53}{6} = 8$

Hence, the other rational number is $\frac{53}{6}$.
