Answer
1$\frac{8}{9}$
Work Step by Step
First, we must remember that an improper fraction is a fraction that has a numerator grater than a denominator.
To convert an improper number to a mixed number, divide the denominator into the numerator and write the mixed number in the following format:
$$ quotient \frac{remainder}{denominator} $$
For the mixed number, when we divide the denominator $17$ into the numerator $9$,
$$17 \div 9 $$
we get the quotient to be $1$ and the remainder to be $8$
Hense, the required mixed number is 1$\frac{8}{9}$.
