Question :

the denominator of a fraction is 3 more than the numerator if 5 is added to both paath the resulting fraction is equivalent to 4/5 find the fraction.

Let the Numerator be x.

Then the Denominator be x + 3

• if 5 is added to both paath the resulting fraction is equivalent to 4/5 .

thus ,

 \frac{x + 5}{x + 3 + 5}  =  \frac{4}{5}

 \frac{x + 5}{x + 8}  =  \frac{4}{5}

5(x + 5) = 4(x + 8)

5x + 25 = 4x + 32

5x - 4x = 32 - 25

{\red{\boxed{\large{\bold{ x \: = 7 }}}}}

Therefore fraction is ;

{\purple{\boxed{\large{\bold{Fraction =\frac{7}{10}}}}}}
