The denominator of the fraction is 5 more than its numerator. if 2is subtracted from both the numerator and the denominator the fraction becomes 4/5.

 \large \bold{To \: Find}

Find the fraction.

 \large \bold{Solution}

Let the Numerator be 'x'.

and, Denominator be '5x'.

According to question.

  =  >  \:  \:  \frac{x \:  -  \: 2}{5x \:  -  \: 2} \:  \:  =  \:  \:   \frac{4}{5}    \\  \\  =  >  \:  \: 5 \: (x \:  -  \: 2) \:  \:  =  \:  \: 4 \: (5x \:  -  \: 2) \\  \\  =  > 5x \:  -  \: 10 \:  \:  =  \:  \: 20x \:  -  \: 8 \\  \\  =  >  \:  \:  - 10 \:  +  \: 8 \:  \:  =  \:  \: 20x \:  -  \: 5x \\  \\  =  >  - 2 \:  \:  =  \:  \: 15x \\  \\  =  >  \:  \: x \:  \:  =  \:  \:   \frac{ - 2}{15}

Answer:

\sf{The  \: fraction \:  is \:  \:  \dfrac{22}{27}}

Step-by-step explanation:

Let,

The numerator of the fraction = x

The denominator of the fraction = x + 5

★ If 2 is subtracted from both the numerator and the denominator

The numerator of the fraction = x - 2

The denominator of the fraction = x + 5 - 2

⇒ x + 5 - 2

x + 3

.°. The denominator of the fraction = x + 3

\sf{\dfrac{x \:  -  \: 2}{x \:  +  \: 3} \:  =  \:  \dfrac{4}{5}}

⇒ 5 (x - 2) = 4 (x + 3)

⇒ 5x - 10 = 4x + 12

⇒ 5x - 4x = 12 + 10

⇒ 1x = 22

x = 22

The numerator of the fraction = 22

The denominator of the fraction = x + 5

⇒ 22 + 5

⇒ 27

The denominator of the fraction = 27

Therefore,

\sf{The  \: fraction \:  is \:  \:  \dfrac{22}{27}}
