Step-by-step solution for: Rounding Numbers
Problem Description:
The task involves rounding each given number to the nearest ten. The numbers are listed in a table, and the solution requires determining the nearest ten for each number.
Solution Approach:
To round a number to the nearest ten:
1. Identify the digit in the ones place of the number.
2. Check if this digit is 5 or greater:
- If it is 5 or greater, round up by increasing the tens digit by 1.
- If it is less than 5, round down by keeping the tens digit the same.
3. Replace the ones digit with 0 to form the rounded number.
Step-by-Step Solution:
#### First Row:
- 237: The ones digit is 7 (greater than 5). Round up: \( 237 \rightarrow 240 \).
- 111: The ones digit is 1 (less than 5). Round down: \( 111 \rightarrow 110 \).
- 213: The ones digit is 3 (less than 5). Round down: \( 213 \rightarrow 210 \).
#### Second Row:
- 762: The ones digit is 2 (less than 5). Round down: \( 762 \rightarrow 760 \).
- 143: The ones digit is 3 (less than 5). Round down: \( 143 \rightarrow 140 \).
- 148: The ones digit is 8 (greater than 5). Round up: \( 148 \rightarrow 150 \).
#### Third Row:
- 1,294: The ones digit is 4 (less than 5). Round down: \( 1,294 \rightarrow 1,290 \).
- 5,090: The ones digit is 0 (already a multiple of 10). No change: \( 5,090 \rightarrow 5,090 \).
- 556: The ones digit is 6 (greater than 5). Round up: \( 556 \rightarrow 560 \).
#### Fourth Row:
- 211: The ones digit is 1 (less than 5). Round down: \( 211 \rightarrow 210 \).
- 712: The ones digit is 2 (less than 5). Round down: \( 712 \rightarrow 710 \).
- 4,344: The ones digit is 4 (less than 5). Round down: \( 4,344 \rightarrow 4,340 \).
#### Fifth Row:
- 256: The ones digit is 6 (greater than 5). Round up: \( 256 \rightarrow 260 \).
- 830: The ones digit is 0 (already a multiple of 10). No change: \( 830 \rightarrow 830 \).
- 5,811: The ones digit is 1 (less than 5). Round down: \( 5,811 \rightarrow 5,810 \).
#### Sixth Row:
- 6,628: The ones digit is 8 (greater than 5). Round up: \( 6,628 \rightarrow 6,630 \).
- 9,420: The ones digit is 0 (already a multiple of 10). No change: \( 9,420 \rightarrow 9,420 \).
- 6,720: The ones digit is 0 (already a multiple of 10). No change: \( 6,720 \rightarrow 6,720 \).
#### Seventh Row:
- 1,290: The ones digit is 0 (already a multiple of 10). No change: \( 1,290 \rightarrow 1,290 \).
- 2,290: The ones digit is 0 (already a multiple of 10). No change: \( 2,290 \rightarrow 2,290 \).
- 356: The ones digit is 6 (greater than 5). Round up: \( 356 \rightarrow 360 \).
#### Eighth Row:
- 873: The ones digit is 3 (less than 5). Round down: \( 873 \rightarrow 870 \).
- 870: The ones digit is 0 (already a multiple of 10). No change: \( 870 \rightarrow 870 \).
- 327: The ones digit is 7 (greater than 5). Round up: \( 327 \rightarrow 330 \).
Final Answer:
\[
\boxed{
\begin{array}{ccc}
237 & 111 & 213 \\
762 & 143 & 148 \\
1,294 & 5,090 & 556 \\
211 & 712 & 4,344 \\
256 & 830 & 5,811 \\
6,628 & 9,420 & 6,720 \\
1,290 & 2,290 & 356 \\
873 & 870 & 327 \\
\end{array}
=
\begin{array}{ccc}
240 & 110 & 210 \\
760 & 140 & 150 \\
1,290 & 5,090 & 560 \\
210 & 710 & 4,340 \\
260 & 830 & 5,810 \\
6,630 & 9,420 & 6,720 \\
1,290 & 2,290 & 360 \\
870 & 870 & 330 \\
\end{array}
}
