## 🎯 Part 1: Round to the Nearest 10

Rule: Look at the ones digit (the digit in the units place).
- If it’s 0–4, round down (keep the tens digit the same).
- If it’s 5–9, round up (increase the tens digit by 1).

Let’s go one by one:

1) 27 → ones digit = 7 → round up → 30
2) 42 → ones digit = 2 → round down → 40
3) 154 → ones digit = 4 → round down → 150
4) 76 → ones digit = 6 → round up → 80
5) 35 → ones digit = 5 → round up → 40
6) 123 → ones digit = 3 → round down → 120
7) 98 → ones digit = 8 → round up → 100
8) 119 → ones digit = 9 → round up → 120
9) 137 → ones digit = 7 → round up → 140
10) 241 → ones digit = 1 → round down → 240
11) 385 → ones digit = 5 → round up → 390
12) 183 → ones digit = 3 → round down → 180
13) 466 → ones digit = 6 → round up → 470
14) 760 → ones digit = 0 → round down → 760
15) 394 → ones digit = 4 → round down → 390
16) 637 → ones digit = 7 → round up → 640
17) 444 → ones digit = 4 → round down → 440
18) 15 → ones digit = 5 → round up → 20
19) 103 → ones digit = 3 → round down → 100
20) 917 → ones digit = 7 → round up → 920
21) 796 → ones digit = 6 → round up → 800

## 🎯 Part 2: Round to the Nearest 100

Rule: Look at the tens digit (the digit in the tens place).
- If it’s 0–4, round down (keep the hundreds digit the same).
- If it’s 5–9, round up (increase the hundreds digit by 1).

Let’s go one by one:

1) 243 → tens digit = 4 → round down → 200
2) 184 → tens digit = 8 → round up → 200
3) 266 → tens digit = 6 → round up → 300
4) 873 → tens digit = 7 → round up → 900
5) 327 → tens digit = 2 → round down → 300
6) 109 → tens digit = 0 → round down → 100
7) 358 → tens digit = 5 → round up → 400
8) 772 → tens digit = 7 → round up → 800
9) 536 → tens digit = 3 → round down → 500
10) 82 → tens digit = 8 → round up → 100 *(since 82 is between 0 and 100, and 8 ≥ 5 → round up to 100)*
11) 916 → tens digit = 1 → round down → 900
12) 447 → tens digit = 4 → round down → 400
13) 752 → tens digit = 5 → round up → 800
14) 707 → tens digit = 0 → round down → 700
15) 364 → tens digit = 6 → round up → 400
16) 436 → tens digit = 3 → round down → 400
17) 750 → tens digit = 5 → round up → 800
18) 347 → tens digit = 4 → round down → 300
19) 782 → tens digit = 8 → round up → 800
20) 158 → tens digit = 5 → round up → 200
21) 954 → tens digit = 5 → round up → 1000

📌 Tip for students: Always underline or circle the digit you’re looking at (ones for nearest 10, tens for nearest 100), then apply the rule. Practice makes perfect!
