Part 1: Round to the Nearest Whole Number

To round to the nearest whole number, look at the tenths place (the first digit after the decimal):

- If it’s 5 or greater, round up.
- If it’s less than 5, round down.

---

1) 5.7 → Tenths digit is 7 → round up → 6
2) 2.8 → Tenths digit is 8 → round up → 3
3) 6.5 → Tenths digit is 5 → round up → 7
4) 8.4 → Tenths digit is 4 → round down → 8
5) 1.4 → Tenths digit is 4 → round down → 1
6) 9.0 → Tenths digit is 0 → already a whole number → 9
7) 4.5 → Tenths digit is 5 → round up → 5
8) 2.4 → Tenths digit is 4 → round down → 2
9) 5.7 → Tenths digit is 7 → round up → 6
10) 9.6 → Tenths digit is 6 → round up → 10
11) 12.3 → Tenths digit is 3 → round down → 12
12) 14.1 → Tenths digit is 1 → round down → 14
13) 17.1 → Tenths digit is 1 → round down → 17
14) 26.6 → Tenths digit is 6 → round up → 27
15) 32.5 → Tenths digit is 5 → round up → 33

Part 2: Round to One Decimal Place

To round to one decimal place, look at the hundredths place (second digit after the decimal):

- If it’s 5 or greater, round the tenths digit up.
- If it’s less than 5, keep the tenths digit same.

---

16) 0.698 → Look at hundredths digit = 9 → round up → 0.7
17) 24.73 → Hundredths digit = 3 → less than 5 → keep → 24.7
18) 3.67 → Hundredths digit = 7 → round up → 3.7
19) 7.53 → Hundredths digit = 3 → less than 5 → keep → 7.5
20) 12.45 → Hundredths digit = 5 → round up → 12.5
