Question

If the number is increased by 5 and the denominator is halved then the resulting fraction is 2 then what is its equation

Answer 1

$\huge\underline{\bold{\red{Answer\::}}}$


If the Numerator is increased by 5.

Let the Numerator be x.

Then; the equation is x + 5.

And the Denominator is halved.

Let the Denominator be y.

Then; the equation is $\dfrac{y}{2}$

Then the resulting fraction is 2.

Fraction = $\dfrac{Numerator}{Denominator}$ = $\dfrac{x}{y}$

A.T.Q.

F = $\dfrac{x}{y}$

$\dfrac{x \: + \: 5}{ \frac{y}{2} }$ = 2

Now cross multiply them

x + 5 = $\dfrac{2\:\times\:y}{2}$

x + 5 = y

$\boxed{x \:-\: y \:= \:- \:5}$
