Explanation:
We are rounding numbers to the nearest 10.
To round to the nearest 10, look at the
ones digit (the last digit):
- If the ones digit is
0–4, round
down (keep the tens digit the same, change ones to 0).
- If the ones digit is
5–9, round
up (add 1 to the tens digit, change ones to 0).
Let’s go through each problem one by one:
1.
2,334 → ones digit = 4 → round down →
2,330
2.
374 → ones digit = 4 → round down →
370
3.
8,202 → ones digit = 2 → round down →
8,200
4.
495 → ones digit = 5 → round up →
500
5.
3,700 → ones digit = 0 → already ends in 0 →
3,700
6.
1,210 → ones digit = 0 → already ends in 0 →
1,210
7.
1,817 → ones digit = 7 → round up →
1,820
8.
5,172 → ones digit = 2 → round down →
5,170
9.
3,731 → ones digit = 1 → round down →
3,730
10.
3,682 → ones digit = 2 → round down →
3,680
11.
9,386 → ones digit = 6 → round up →
9,390
12.
331 → ones digit = 1 → round down →
330
13.
2,949 → ones digit = 9 → round up →
2,950
14.
6,018 → ones digit = 8 → round up →
6,020
15.
8,262 → ones digit = 2 → round down →
8,260
16.
8,090 → ones digit = 0 → already ends in 0 →
8,090
17.
6,075 → ones digit = 5 → round up →
6,080
18.
971 → ones digit = 1 → round down →
970
19.
2,979 → ones digit = 9 → round up →
2,980
20.
6,754 → ones digit = 4 → round down →
6,750
21.
8,065 → ones digit = 5 → round up →
8,070
Double-check a few tricky ones:
- 495 → 495 is halfway between 490 and 500; rule says round *up* when ≥5 → 500
✔
- 6,075 → 75 → round to 80 → 6,080
✔
- 2,979 → 79 → round to 80 → 2,980
✔
All correct.
