Question

the denominator of a fraction is 4 more then twice the numerator when both the numerator and denominator are decreased by 6 then the denominator becomes 12 times the numerator then the fraction is​

Answer 1

Denominator 4 more than twice the a Numerator .

Let Numerator=x

Then Denominator will be=2x+4

$fraction = \frac{x}{2x + 4}$

Now 6 is Decreased by Numerator and Denominator.

$\frac{x - 6}{2x + 4 - 6} \\ \\ \frac{x - 6}{2x - 2}$

Denominator now is 12 times the Numerator now

Denominator now=12×(Numerator now)

2x-2=12(x-6)

2x-2=12x-72

2x-12x=-72+2

-10x=-70

x=-70/-10

x=7

Numerator=x=7

Denominator=2x+4=2×7+4=18

Fraction=7/18

$\underline{\mathbf{\huge{Fraction=\frac{7}{18}}}}$
