Question

3.find (x+y)÷(x-y) if
1.x=5÷2,y=-3÷4
2.x=1÷4,y=3÷2
​

Answer 1

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

Answer 2

Answer:

1. 4

2. -1.4

Step-by-step explanation:

1. x= 5÷2, y= 3÷4

⇒Given,

x= 5÷2

= 2.5

y= 3÷4

= 1.5

So,

 (x+y)÷(x-y)

= (2.5+1.5)÷(2.5-1.5)

= 4÷1

= 4

2. x= 1÷4, y= 3÷4

⇒Given,

x= 1÷5

 = 0.25

y= 3÷2

 = 1.5

So,

 (x+y)÷(x-y)

= (0.25+1.5)÷(0.25-1.5)

= 1.75÷(-1.25)

= -1.4
