Question

find:(x+y)÷(x-y) when x=5/2,y=(-3/4)​

Answer 1

Given: x=5/2, y=-3/4​

x+y = 5/2 - 3/4 = (10-3)/4 =7/4

x-y = 5/2 -( -3/4) = (10+3)/4 = 13/4

Answer 2

Answer:

we have to find first X+Y

X+Y= 5/2 + (-3/4)

 = 5/2-3/4=>10-3/4=> 7/4

Now we find X-Y

X-Y= 5/2 - (-3/4) => 5/2 + 3/4=>10+3/4 =>13/4

Now X+Y/X-Y= (7/4) / (13/4) => 7/13
