Question

The sum of two rational numbers is 5, one of the number is 13/6, then
the other number is____

Answer 1

➤ Answer :-

${\tt \longrightarrow \dfrac{13}{6} + \sf (x) = \tt 5}$

To find the value of 'x' in the following sum, we should subtract the answer and the first value............

${\sf \longrightarrow (x) = \tt 5 - \dfrac{13}{6}}$

${\tt \longrightarrow \dfrac{5}{1} - \dfrac{13}{6}}$

Convert them into like fractions by taking the LCM of the denominators i.e, 1 and 6.

LCM of 1 and 6 is 6.

${\tt \longrightarrow \dfrac{5 \times 6}{1 \times 6} - \dfrac{13}{6}}$

${\tt \longrightarrow \dfrac{30}{6} - \dfrac{13}{6} = \dfrac{30 - 13}{6}}$

${\tt \longrightarrow \dfrac{17}{6} = 2 \dfrac{5}{6}}$

$\Huge\therefore$ The other number is ${\tt\dfrac{17}{6}}$ or $\tt 2 \dfrac{5}{6}$

Answer 2

Answer:

Let the second be x.

ATQ

x + 13/6 = 5

x = 5 - 13/6

x = 17/6
