Question

The sum of two rational number is -2.If one of the number is -14/5 ,find the other.

​

Answer 1

Let the other rational number be ‘x’
Given, x+(-14/5)=-2
So x-(14/5)= -2
x=-2+(14/5)
x=4/5

Answer 2

Answer:

Other rational number is 4/5 .

Step-by-step explanation:

Given -

The sum of two rational number is -2.

One of the  rational number is $\frac{-14}{5}$ .

To find -

Other rational number

Solution -

Let, other rational number is $x$

As per given information

$\frac{-14}{5} + x =-2$

$x = -2 + \frac{14}{5}$

For subtraction of fraction number both the denominator should be same.

Multiply 2 by 5/5 we get

$x = \frac{-10}{5} +\frac{14}{5}$

$x = \frac{-10+14}{5}$

$x=\frac{4}{5}$

∴ Other rational number is 4/5 .

LHS = $\frac{-14}{5} + \frac{4}{5}$ = $\frac{-14+4}{5}$= $\frac{-10}{5}$ = $-2$

LHS = RHS

∴ Ans checked
