(1) The numerator and the denominator of a fraction are in the ratio 3 : 2. if
3 is added to the
numerator and 2 is subtracted from the denominator, a new fraction is formed whese value is
Find the original fraction.
Answers
To Find:-
- Find the original fraction.
Given:-
- Numerator and the denominator of a fraction are in the ratio 3 : 2
- 3 is added to the numerator and 2 is subtracted from the denominator.
Solution:-
Let the fraction be 3x/2x
(3x + 3)/(2x - 2) = 9/4
➭ 4( 3x + 3 ) = 9( 2x - 2 )
➭ 12x + 12 = 18x - 18
➭ 18x - 12x = 18 + 12
➭ 6x = 30
➭ x = 30/6
➭
So,
The fraction is
➭ 3x / 2x = 15/10

Find the original fraction.
: We have to find the original fraction = ??
: Ratio of numerator and denominator of the fraction = 3 : 2
: Let the numerator be 3x and denominator be 2x.
: If 3 is added to the numerator and 2 is subtracted from the denominator =
:
: 4(3x + 3) = 9(2x - 2)
: 12x + 12 = 18x - 18
: 12 + 18 = 18x - 12x
: 30 = 6x
:
: 5 = x
:
● Numerator of the fraction = 3x = 3(5) = 15.
● Denominator of the fraction = 2x = 2(5) = 10.
