Question

the sum of two rational number is -3 if one of them is -3 by 13 find the other number​

Answer 1

let another be x

-3 + x= -3/ 13

x= -3/13+ 3= 36/ 13 is another number

Answer 2

Answer:

The required rational number is found to be: $-\frac{36}{13}$.

Explanation:

Rational Numbers:

Rational number, in arithmetic, variety that can be represented as the quotient, p/q of two integers such that q ≠ 0. additionally to all the fractions, the set of rational numbers includes all the integers, each of which may be written as a quotient with the integer as the numerator and 1 as the denominator. In decimal format, rational numbers end or cycle through decimal numbers.

Calculations:

The sum of the given two rational numbers is given to us as: -3

One of the number is given to us as: $-\frac{3}{13}$

Now, assuming the other rational number as 'x', we get the expression as:

$x+(-\frac{3}{13})=-3$

Separating the variables from the known values, we get:

$x=-3+\frac{3}{13}$

Taking the LCM, we get the expression modified as:

$x=\frac{-39+3}{13}$

Simplifying it, we get:

$x=-\frac{36}{13}$

The required rational number is found to be: $-\frac{36}{13}$.
