Answer 1

the answer is 7/13
Substitute the given values as fractions in the equation and take their LCM...then solve it easily. I hope it helps.

Answer 2

Answer:

$\frac{7}{13}$

Step-by-step explanation:

In the question

The given expression is

(x + y) ÷ (x - y)                                            ........(i)

Where, $x = \frac{5}{2}$ and $y = -\frac{3}{4}$

Put the value of x and y in equation (i)

$[{\frac{5}{2}\ +\ (-\frac{3}{4})]$ ÷ $[{\frac{5}{2}\ -\ (-\frac{3}{4})]$

=  $(\frac{5}{2}\ -\frac{3}{4})$ ÷  $(\frac{5}{2}\ +\frac{3}{4})$

= $(\frac{10\ -\ 3}{4})$ ÷ $(\frac{10\ +\ 3}{4})$

= $\frac{7}{4}$ ÷ $\frac{13}{4}$

= $\frac{7}{4}$ x $\frac{4}{13}$

= $\frac{7}{13}$ (Answer)
