Work Step by Step
$\frac{17}{5} - \frac{2}{5}$
The difference of two fractions with same denominators is the difference of their numerators over the common denominator.
$\frac{17-2}{5}$ = $\frac{15}{5}$
Since 5 is the greatest common factor of 15 and 5, divide numerator and denominator by 5
$\frac{3*5}{1*5}$ = 3
