Tony is given the following quiz: Round $\frac{5}{11} = 0.\overline{45}$ to the nearest

$\bullet$ 1) whole number

$\bullet$ 2) tenth

$\bullet$3) hundredth

$\bullet$ 4) thousandth

$\bullet$ 5) ten thousandth

$\bullet$ 6) hundred thousandth

Tony completes the quiz as follows. He first (correctly) rounds $0.\overline{45}$ to the nearest hundred thousandth, and writes it as his answer for question 6. Then he rounds his answer for question 6 to the nearest ten thousandth and uses that as his answer for question 5. Then he rounds his answer for question 5 to the nearest thousandth and uses that as his answer for question 4. Then he rounds his answer for question 4 to the nearest hundredth and uses that as his answer for question 3. Then he rounds his answer for question 3 to the nearest tenth and uses that as his answer for question 2. Finally, he rounds his answer for question 2 to the nearest whole number, uses that as his answer for question 1, and turns in the quiz. How many questions does Tony get wrong?
