Question

find (x+y)÷(x-y) if x=5/2 y=-3/4​

Answer 1

Answer:

$( \frac{5}{2} + ( - \frac{3}{4} )) \div ( \frac{5}{2} - ( - \frac{3}{4} )) \\ ( \frac{5}{2} - \frac{3}{4} ) \div ( \frac{5}{2} + \frac{3}{4} ) \\ ( \frac{10 - 3}{4} ) \div ( \frac{10 + 3}{4} ) \\ \frac{7}{3} \div \frac{13}{4} = \frac{7}{3} \times \frac{4}{13} \\ \frac{28}{39}$

28/39 is the answer.

Answer 2

Step-by-step explanation:

Here,

if

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

now, we have to find out the value

so,

$\frac{x + y}{x - y}$

$= \frac{7}{13}$
