Question

The sum of two rational numbers is -3. If one of them is (-10)/3 ,

then find the other number.
​

Answer 1

$Let \: x \: and \: y\: are\: two \: rational \\numbers .$

$Let \: one \:number \: (x )= \frac{-10}{3}$

$\red{Other\: number = y}$

/* According to the problem , given */

$Sum \: of \:two \: numbers = -3$

$\implies x + y = -3$

$\implies \frac{-10}{3} + y = -3$

$\implies y = \frac{10}{3} - 3$

$\implies y = \frac{10 - 9}{3}$

$\implies y = \frac{1}{3}$

Therefore.,

$\red{ Required \:other \: number } \green {= \frac{1}{3}}$
