Answer 1

Answer:

6by 15 is the answer of the question

Answer 2

Answer:

The value of Other rational number is 33/10 .

Step-by-step explanation:

Given -

Sum of two rational numbers are is $\frac{13}{5}$

one other numbers is $\frac{-7}{10}$

To find -

Other rational number

Solution -

Let, Other rational number is x .

We can given information as,

Sum of two rational numbers are is $\frac{13}{5}$

$x+ \frac{(-7)}{10} = \frac{13}{5}$

$x- \frac{7}{10} = \frac{13}{5}$

$x= \frac{13}{5} + \frac{7}{10}$

For subtraction of rational number both the denominator should be same.

Multiply 13/5 by 2/2 we get,

$x= \frac{26}{10} + \frac{7}{10}$

$x=\frac{26+7}{10}$

$x=\frac{33}{10}$

∴ The value of Other rational number is 33/10 .
