Answer:
Let,
[tex]\mapsto \bf Numerator =\: y\\[/tex]
[tex]\bigstar[/tex] The denominator of a fraction is twice the numerator.
[tex]\mapsto \bf Denominator =\: 2y\\[/tex]
So, the required fraction become :
[tex]\leadsto \sf Fraction =\: \dfrac{Numerator}{Denominator}\\[/tex]
[tex]\leadsto \sf\bold{Fraction =\: \dfrac{y}{2y}}\\[/tex]
❒ According to the question :
[tex]\bigstar[/tex] When both are increased by 2, the fraction become 3/4.
So,
[tex]\implies \sf\boxed{\bold{\bigg\{\dfrac{Numerator + 2}{Denominator + 2}\bigg\} =\: \bigg\{\dfrac{3}{4}\bigg\}}}\\[/tex]
[tex]\implies \sf \dfrac{y + 2}{2y + 2} =\: \dfrac{3}{4}\\[/tex]
By doing cross multiplication we get,
[tex]\implies \sf 3(2y + 2) =\: 4(y + 2)\\[/tex]
[tex]\implies \sf 6y + 6 =\: 4y + 8\\[/tex]
[tex]\implies \sf 6y - 4y =\: 8 - 6\\[/tex]
[tex]\implies \sf 2y =\: 2\\[/tex]
[tex]\implies \sf y =\: \dfrac{\cancel{2}}{\cancel{2}}\\[/tex]
[tex]\implies \sf y =\: \dfrac{1}{1}\\[/tex]
[tex]\implies \sf\bold{y =\: 1}\\[/tex]
Hence, the required fraction will be :
[tex]\dag[/tex] Required Fraction :
[tex]\dashrightarrow \sf Required\: Fraction =\: \dfrac{y}{2y}\\[/tex]
[tex]\dashrightarrow \sf Required\: Fraction =\: \dfrac{1}{2(1)}\\[/tex]
[tex]\dashrightarrow \sf Required\: Fraction =\: \dfrac{1}{2 \times 1}\\[/tex]
[tex]\dashrightarrow \sf\bold{\underline{Required\: Fraction =\: \dfrac{1}{2}}}\\[/tex]
[tex]\small \sf\boxed{\bold{\therefore\: The\: required\: fraction\: is\: \dfrac{1}{2}\: .}}\\[/tex]
