Question

Ony is given the following quiz:

Round $5/11 = 0.\overline{45}$ to the nearest
1) whole number
2) tenth
3) hundredth
4) thousandth
5) ten thousandth
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.

Answer 1

Explanation:

1. To round $5/11 = 0.\overline{45}$ to the nearest whole number, we look at the digit in the ones place, which is 5. Since 5 is greater than or equal to 5, we round up to the next whole number, which is 1. Therefore, rounded to the nearest whole number, $5/11$ is equal to 1.

2. To round $5/11 = 0.\overline{45}$ to the nearest tenth, we look at the digit in the hundredth place, which is 5. Since 5 is greater than or equal to 5, we round up to the next tenth, which is 0.5. Therefore, rounded to the nearest tenth, $5/11$ is equal to 0.5.

3. To round $5/11 = 0.\overline{45}$ to the nearest hundredth, we look at the digit in the thousandth place, which is also 5. Since 5 is greater than or equal to 5, we round up to the next hundredth, which is 0.46. Therefore, rounded to the nearest hundredth, $5/11$ is equal to 0.46.

4. To round $5/11 = 0.\overline{45}$ to the nearest thousandth, we look at the digit in the ten thousandth place, which is 4. Since 4 is less than 5, we round down to 0.455. Therefore, rounded to the nearest thousandth, $5/11$ is equal to 0.455.

5. To round $5/11 = 0.\overline{45}$ to the nearest ten thousandth, we look at the digit in the hundred thousandth place, which is 5. Since 5 is equal to 5, we round up if the digit in the ten thousandth place is odd, and round down if it is even. In this case, the digit in the ten thousandth place is 4, which is even, so we round down to 0.4550. Therefore, rounded to the nearest ten thousandth, $5/11$ is equal to 0.4550.

6. To round $5/11 = 0.\overline{45}$ to the nearest hundred thousandth, we look at the digit in the millionth place, which is also 5. Since 5 is equal to 5, we round up if the digit in the hundred thousandth place is odd, and round down if it is even. In this case, the digit in the hundred thousandth place is even, so we round down to 0.45499. Therefore, rounded to the nearest hundred thousandth, $5/11$ is equal to 0.45499.

When Tony rounds $0.\overline{45}$ to the nearest hundred thousandth, he gets 0.45499, which he then rounds to 0.4550, and so on, following the same steps we did above. His final answer for question 1 will be 0, since rounding 0.5 to the nearest whole number gives 0. Therefore, Tony's final answers will be:

1. 0

2. 0

3. 0.46

4. 0.455

5. 0.4550

6. 0.45499
