Answer 1

Answer:

Given:-

Numerator : Denominator = 3 : 5

If 4 subtracted from numerator it reduces 1 by 5.

To Find:-

The Fraction

Solution:-

Let numerator be 3x3x

And denominator be 5x5x

So, Fraction will be \dfrac{3x}{5x}

5x

3x

According to question,

New numerator will be = 3x-43x−4

Which gives \dfrac{1}{5}

5

1

So new fraction:

⇒ \dfrac{3x - 4}{5x} = \dfrac{1}{5}⇒

5x

3x−4

=

5

1

⇒5×(3x-4)=5x⇒5×(3x−4)=5x

⇒15x−20=5x⇒15x−20=5x

⇒15x−5x=20⇒15x−5x=20

⇒10x=20⇒10x=20

⇒x=2⇒x=2

Fraction = \dfrac{3x}{5x}

5x

3x

= \dfrac{3×2}{5×2}

5×2

3×2

= \dfrac{6}{10}

10
