Question

The sum of two rational numbers is 2/5. If one of them is -4/7,find the other

Answer 1

Let the other no .be x
then, x+(-4/7)=2/5
:- x-4/7=2/5
:- x=2/5+4/7
:- x=14+20/35
:- x=34/35. ans ......

Answer 2

Answer:  $\frac{34}{35}$

Step-by-step explanation:

We know that one of the two rational number is given and other is not given

Let us consider the other number be x.

then, x + $(\frac{-4}{7})$ =  $\frac{2}{5}$

x =  $\frac{2}{5}$ + $\frac{4}{7}$

x = $\frac{14+20}{35}$

x = $\frac{34}{35}$ .

• Here in this problem they have asked to find a rational number that when added with the given number it gives the sum  $\frac{2}{5}$ .
• An equation according to the data is formed but leaving the unknown number denoted as x .
• Now solve for x and we will find the final answer as the above solution.
