Question

The denominator of a fraction is greater than the

numerator by 4. If 1 is subtracted from the

numerator and 3 is added to the denominator, the

value of the fraction obtained is 1

3

. Find the original

fraction.

can anybody only form the equation plz....
​

Answer 1

Answer:

The denominator of a fraction is 4 more than its numerator

so

let numberator be x 

then denomintor is x +4

now,

on subtracting 1 from each the number and the denominator.the fraction become 1/2

lets form an equation

x  - 1/ (x + 4)  -1 = 1/2

x  - 1/ x + 3 = 1/2

lets cross multiply

2(x - 1) = 1(x + 3)

2x - 2 = x +3

2x - x = 2 +3

x = 5

now denominator is x +4

= 5+4 = 9

so fraction is 5/9

:)

Answer 2

Answer:

kindly see the answer below...

Step-by-step explanation:

Here,

let the original fraction be

$= \frac{x}{x + 4}$

then, according to the question..

$here \: \: \frac{x - 1}{x + 4 + 3} = \frac{1}{3}$

$or \: \: 3x - 3 = x + 7$

$or \: \: 2x = 10$

$or \: \: x = 5$

so, the original fraction is

$= \frac{x}{x + 4}$

$= \frac{5}{9}$

thanks a lot...
