Problem Description:
The task is to round the given numbers to the nearest 10. The first number has been rounded as an example:
31 rounds to
30.
Steps to Solve:
1.
Understanding Rounding to the Nearest 10:
- If the digit in the ones place is
5 or greater, round up to the next multiple of 10.
- If the digit in the ones place is
less than 5, round down to the previous multiple of 10.
2.
Apply the Rule to Each Number:
- For each number, look at the digit in the ones place and apply the rounding rule.
Solution:
#### First Row:
-
56: The ones digit is 6 (greater than 5), so round up to
60.
-
64: The ones digit is 4 (less than 5), so round down to
60.
#### Second Row:
-
17: The ones digit is 7 (greater than 5), so round up to
20.
-
22: The ones digit is 2 (less than 5), so round down to
20.
-
89: The ones digit is 9 (greater than 5), so round up to
90.
#### Third Row:
-
95: The ones digit is 5 (equal to 5), so round up to
100.
-
73: The ones digit is 3 (less than 5), so round down to
70.
-
46: The ones digit is 6 (greater than 5), so round up to
50.
#### Fourth Row:
-
29: The ones digit is 9 (greater than 5), so round up to
30.
-
12: The ones digit is 2 (less than 5), so round down to
10.
-
38: The ones digit is 8 (greater than 5), so round up to
40.
#### Fifth Row:
-
67: The ones digit is 7 (greater than 5), so round up to
70.
-
83: The ones digit is 3 (less than 5), so round down to
80.
-
99: The ones digit is 9 (greater than 5), so round up to
100.
#### Sixth Row:
-
43: The ones digit is 3 (less than 5), so round down to
40.
-
38: The ones digit is 8 (greater than 5), so round up to
40.
-
55: The ones digit is 5 (equal to 5), so round up to
60.
Final Answer:
\[
\begin{array}{ccc}
31 = 30 & 56 = 60 & 64 = 60 \\
17 = 20 & 22 = 20 & 89 = 90 \\
95 = 100 & 73 = 70 & 46 = 50 \\
29 = 30 & 12 = 10 & 38 = 40 \\
67 = 70 & 83 = 80 & 99 = 100 \\
43 = 40 & 38 = 40 & 55 = 60 \\
\end{array}
\]
Boxed Final Answer:
\[
\boxed{
\begin{array}{ccc}
30 & 60 & 60 \\
20 & 20 & 90 \\
100 & 70 & 50 \\
30 & 10 & 40 \\
70 & 80 & 100 \\
40 & 40 & 60 \\
\end{array}
}
\]
