Question

divide the sun of 3/4 and -4/7 by their difference?​

Answer 1

Solution

Steps to solve :

1. Find the sum of 3/4 and -4/7

2. Find the difference of 3/4 and -4/7

3. Divide the sum with difference.

===================

Now come to the

your question

===================

Given :

The number of which we

do sum and difference

= $\dfrac{3}{4}\:and\:-\dfrac{4}{7}$

===================

To find :

The number.

===================

According to question firstly

we find the sum of 3/4 and

-4/7 and after that we find their

difference.After getting the sum

and difference we divide it.

===================

According to step first

we are going to find sum.

$\implies\dfrac{3}{4}+\dfrac{-4}{7}\\\\\\=\dfrac{21+(-16)}{28}\\\\\\=\dfrac{5}{28}\\\\\\\\\Huge{\boxed{Sum=\dfrac{5}{28}}}$

===================

According to step second

we are going to find their

difference.

$\implies\dfrac{3}{4}-\dfrac{(-4)}{7}\\\\\\=\dfrac{21-(-16)}{28}\\\\\\=\dfrac{37}{28}\\\\\\\\\Huge{\boxed{Difference=\dfrac{37}{28}}}$

===================

According to third and

last step we are going

to divide  the sun of 3/4 and

-4/7 by their difference

$\implies\dfrac{5}{28}\div\dfrac{37}{28}\\\\\\=\dfrac{5}{28}\times\dfrac{28}{37}\\\\\\=\dfrac{5}{37}\\\\\\\\\Huge{\boxed{Division=\dfrac{5}{37}}}$

===================

Answer : 5/37
