Question

the sum of two rational number is 1/10.IF ONE NUMBER IS 3/5 .​

Answer 1

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

$numbers .$

$Given \: x = \frac{3}{5}$

/* According to the problem given */

$x + y = \frac{1}{10}$

$\implies \frac{3}{5} + y = \frac{1}{10}$

$\implies y = \frac{1}{10} - \frac{3}{5}$

$= \frac{ 1 - 6}{10}$

$= \frac{-5}{10}$

$= \frac{-1}{2}$

Therefore.,

$\red{ Required \: number }\green { = \frac{-1}{2}}$

Answer 2

Given :

• Sum of two rational number is $\sf\dfrac{1}{10}$
• If one number is $\sf\dfrac{3}{5}$

To find :

• Other number

According to the question,

Let the other number be x

$\rightarrow\sf{x + \frac{3}{5} = \frac{1}{10} }$

$\rightarrow \sf{x = \frac{1}{10} - \frac{3}{5} }$

$\rightarrow\sf{x = \frac{1 - 6}{10} }$

$\rightarrow\sf{x = \cancel \frac{ - 5}{10} }$

$\rightarrow\sf \red{x = \frac{ -1}{2}}}$

So,the answer is -1/2
