if we add 1 to the numerator and subtract 1 from the denominator of fraction reduces to one it becomes 1 upon 2 if we only add one to the denominator what is the fraction
Answers
Answer:
Numerator = 3
Denominator = 5
Therefore , 3/5
Step-by-step explanation
.
Let the fraction be x/y .
Now as per given ,
x+1/y-1 = 1
therefore, x-y=(-2).........................(eq.1)
x/y+1=1/2
therefore, 2x-y=1............................(eq.2)
Subtraction of eq 1 from 2 ...
We get x=3.
Substituting in eq 2.
We get ...
2x-y=1
2(3) - y = 1
6-y=1
(-y) = 1-6
-y=-5
Therefore,y= 5.
Suppose the fraction is x/y
If 1 is added to the numerator and 1 is subtracted to the denominator the fraction becomes 1
x+1/y-1 =1
=>x+1=y−1
=> x−y=−2 Equation (1)
If 1 is added to the denominator the fraction becomes half
x/y+1 = 1/2
=> 2x=y+1
2x−y=1 Equation (2)
On subtracting Equation 1 from 2 we get
2x−y−x+y=1+2
x=3
Substituting the value of x in equation 1 we get,
3−y=−2
y=5
