Question

The numerator of a fraction is three less than its denominator If both the numerator and the denominator of the function are increased by 5, then the resulting fraction is equal to 3/4.find the original fraction?​

Answer 1

Answer:

4/7

Step-by-step explanation:

let

$fraction = \frac{a}{b}$

a=b-3------eqn 1

$\frac{b - 3+ 5}{b + 5} = \frac{3}{4}$

$\frac{b + 2}{b + 5} = \frac{3}{4}$

4b+8=3b+15

b=7

therefore a= 4

therefore the fraction =4/7
