Question

the sum of 2 ration number is 5/26 if one of them is -7/26 then find other​

Answer 1

Answer:

hence,

5/26-(-7/26)

5-(-7)/26

12/26

6/13

let me know if it's incorrect

Answer 2

QUESTION:

• The sum of 2 rational numbers is 5/26. If one of them is -7/26, then find the other rational number.

ANSWER:

Given:

• Sum of 2 rational nos = 5/26
• One rational no. = -7/26

To Find:

• Other rational no.

Solution:

Let us assume that the other rational number is x.

We are given that,

$\implies\text{Sum of 2 rational nos}=\dfrac{5}{26}$

So,

$\implies x+\dfrac{-7}{26}=\dfrac{5}{26}$

$\implies x-\dfrac{7}{26}=\dfrac{5}{26}$

Transposing 7/26 to RHS,

$\implies x=\dfrac{5}{26}+\dfrac{7}{26}$

As the denominator is same, hence the LCM is 26 only.

Combining the fractions,

$\implies x=\dfrac{5}{26}+\dfrac{7}{26}$

$\implies x=\dfrac{5+7}{26}$

$\implies x=\dfrac{12}{26}$

Dividing the numerator and denominator by 2,

$\implies x=\dfrac{(12\div2)}{(26\div2)}$

$\implies\bf x=\dfrac{6}{13}$

Therefore, the other rational number is 6/13.
