To round a number to the nearest 10, look at the digit in the ones place (the last digit):
- If it’s 5 or more, round up.
- If it’s less than 5, round down.
Let’s go through each number:
1.
82 → ones digit is 2 → less than 5 → round down →
80
2.
84 → ones digit is 4 → less than 5 → round down →
80
3.
92 → ones digit is 2 → less than 5 → round down →
90
4.
51 → ones digit is 1 → less than 5 → round down →
50
5.
13 → ones digit is 3 → less than 5 → round down →
10
6.
70 → already a multiple of 10 → stays
70
7.
66 → ones digit is 6 → 5 or more → round up →
70
8.
97 → ones digit is 7 → 5 or more → round up →
100
9.
87 → ones digit is 7 → 5 or more → round up →
90
10.
29 → ones digit is 9 → 5 or more → round up →
30
11.
71 → ones digit is 1 → less than 5 → round down →
70
12.
78 → ones digit is 8 → 5 or more → round up →
80
13.
28 → ones digit is 8 → 5 or more → round up →
30
14.
36 → ones digit is 6 → 5 or more → round up →
40
15.
57 → ones digit is 7 → 5 or more → round up →
60
16.
24 → ones digit is 4 → less than 5 → round down →
20
17.
47 → ones digit is 7 → 5 or more → round up →
