The numerator

The numerator of the fraction is 5 more than its denominator. If 4 is added to the numerator and denominator, the fraction obtained is 6/5.

What is that fraction?

Final Answer:

f =  26/21 = 1 ⁵⁄₂₁

Step-by-step explanation:

$$\begin{gathered} f=\frac{5+d}{d} \\ \frac{5+d+4}{d+4}=\frac{6}{5} \\ \frac{d+9}{d+4}=\frac{6}{5} \\ 5\cdot (d+9)=6\cdot (d+4) \\ d=21 \\ f=\frac{5+d}{d}=\frac{5+21}{21}=\frac{26}{21}=1\frac{5}{21}=1.2381 \end{gathered}$$
