Question-----»»
A fraction is such that numerator is 2 less than denominator.if u add 3 to numerator and 5 to denominator resulting fraction is equivalent to original fraction. find fraction
Answer
Let the denominator of the fraction be x
Now, According to question
Numerator is 2 times less than denominator. Therefore The fraction we get is -
x-2/x
After adding 3 to numerator and 5 to the denominator resulting fraction is equals to the original fraction -
therefore -
x-2+3/x+5 = x-2/x
x+1/x+5 = x-2/x
Now by cross multiplication
(x+1)(x) = (x-2)(x+5)
x^2 + x = x^2 + 5x - 2x - 10
x = 5x - 2x - 10
x = 3x - 10
x - 3x = -10
-2x = -10
x = -10/-2
x = 5
Verification -
By putting the value of x we get -
5-2+3/5+5 = 5-2/5
3+3/10 = 3/5
6/10 = 3/5
3/5 = 3/5
Therefore the fraction is 3/5

Answer:
3/5
Step-by-step explanation:
Given that the fraction's numerator is 2 less than the denominator .
We can assume the numerator to be x .
Then the fraction looks like :
x / ( x + 2 )
Now if we add 3 to numerator , it will become x + 3
If we add 5 to the denominator , it becomes x + 2 + 5
= x + 7
Now that the fraction becomes 3/5 we can write this as :
( x + 3 )/ ( x + 7 ) = 3/5
= 5 ( x + 3 ) = 3 ( x + 7 )
= 5 x + 15 = 3 x + 21
= 2 x = 6
= x = 6/2
= x 3
Faction is 3/3+2
= 3/5
The answer is 3/5 .
3 + 3 / 5 + 5
= 6/10
= 3/5
Hence verified answer !
