Question

The sum of two rational no. is -14/15. If first no is -3 . Find the other.​

Answer 1

Answer:

31/15

the first number is (-3)

then the second number is to be X

(-3)+X= -14/15

X= -14/15 + 3

X= (-14+45) / 15

X = 31/15

⠀⠀⠀⠀⠀

Let the other number be x.

So, According to question

$\implies \tt \: x + ( - 3) = \frac{ - 14}{15}$

$\implies \tt \: x - 3 = \frac{ - 14}{15}$

$\implies \tt \: x = \frac{ - 14}{15}+3$

$\implies \tt \: x = \frac{ - 14 + 45}{15}$

$\implies \tt \: x = \frac{31}{15}$

⠀⠀⠀⠀⠀

Verification:-

$\implies \tt \: x + ( - 3) = \frac{ - 14}{15}$

• Put x = 31/15.

$\implies \tt \:\frac{31}{15} -3 = \frac{ - 14}{15}$

$\implies \tt \:\frac{31 - 45}{15}= \frac{ - 14}{15}$

$\implies \tt \:\frac{-14}{15}= \frac{ - 14}{15}$

Hence, verified

⠀⠀⠀⠀⠀

Thus, Other number is 31/15
