Problem Description:
The task involves rounding numbers to the nearest whole number and then rounding them to two decimal places. The worksheet provides a series of numbers that need to be rounded according to these instructions.
Solution Approach:
1.
Rounding to the Nearest Whole Number:
- To round a number to the nearest whole number, look at the digit in the tenths place (the first digit after the decimal point).
- If the tenths digit is 5 or greater, round up.
- If the tenths digit is less than 5, round down.
2.
Rounding to Two Decimal Places:
- To round a number to two decimal places, look at the digit in the thousandths place (the third digit after the decimal point).
- If the thousandths digit is 5 or greater, round up the hundredths digit.
- If the thousandths digit is less than 5, keep the hundredths digit as it is.
Step-by-Step Solution:
#### Part 1: Round Each Number to the Nearest Whole Number
1.
3.99: The tenths digit is 9 (greater than 5), so round up.
- Rounded to the nearest whole number:
4
2.
5.26: The tenths digit is 2 (less than 5), so round down.
- Rounded to the nearest whole number:
5
3.
0.82: The tenths digit is 8 (greater than 5), so round up.
- Rounded to the nearest whole number:
1
4.
7.32: The tenths digit is 3 (less than 5), so round down.
- Rounded to the nearest whole number:
7
#### Part 2: Round Each Number to Two Decimal Places
1.
4.83: The thousandths digit is 0 (less than 5), so keep the hundredths digit as it is.
- Rounded to two decimal places:
4.83
2.
9.31: The thousandths digit is 0 (less than 5), so keep the hundredths digit as it is.
- Rounded to two decimal places:
9.31
3.
7.05: The thousandths digit is 0 (less than 5), so keep the hundredths digit as it is.
- Rounded to two decimal places:
7.05
4.
0.13: The thousandths digit is 0 (less than 5), so keep the hundredths digit as it is.
- Rounded to two decimal places:
0.13
#### Part 3: Round Each Number to Two Decimal Places
1.
1.27: The thousandths digit is 0 (less than 5), so keep the hundredths digit as it is.
- Rounded to two decimal places:
1.27
2.
13.26: The thousandths digit is 0 (less than 5), so keep the hundredths digit as it is.
- Rounded to two decimal places:
13.26
3.
24.36: The thousandths digit is 0 (less than 5), so keep the hundredths digit as it is.
- Rounded to two decimal places:
24.36
4.
6.47: The thousandths digit is 0 (less than 5), so keep the hundredths digit as it is.
- Rounded to two decimal places:
6.47
Final Answer:
\[
\boxed{
\begin{array}{c|c|c}
\text{Number} & \text{Nearest Whole Number} & \text{Two Decimal Places} \\
\hline
3.99 & 4 & 4.00 \\
5.26 & 5 & 5.26 \\
0.82 & 1 & 0.82 \\
7.32 & 7 & 7.32 \\
4.83 & 5 & 4.83 \\
9.31 & 9 & 9.31 \\
7.05 & 7 & 7.05 \\
0.13 & 0 & 0.13 \\
1.27 & 1 & 1.27 \\
13.26 & 13 & 13.26 \\
24.36 & 24 & 24.36 \\
6.47 & 6 & 6.47 \\
\end{array}
}
