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 is 5 or more, round up.
- If it is less than 5, round down.

1) 3.94 → tenths digit is 9 → round up → 4
2) 12.14 → tenths digit is 1 → round down → 12
3) 23.2 → tenths digit is 2 → round down → 23
4) 15.26 → tenths digit is 2 → round down → 15
5) 14.52 → tenths digit is 5 → round up → 15
6) 12.38 → tenths digit is 3 → round down → 12
7) 90.82 → tenths digit is 8 → round up → 91
8) 24.59 → tenths digit is 5 → round up → 25
9) 63.08 → tenths digit is 0 → round down → 63
10) 29.51 → tenths digit is 5 → round up → 30
11) 38.74 → tenths digit is 7 → round up → 39
12) 118.4 → tenths digit is 4 → round down → 118

Part 2: Round to the nearest tenth

To round to the nearest tenth, look at the hundredths place (second digit after decimal).
- If it is 5 or more, round up the tenths digit.
- If it is less than 5, keep the tenths digit the same.

1) 4.83 → hundredths digit is 3 → round down → 4.8
2) 1.94 → hundredths digit is 4 → round down → 1.9
3) 15.28 → hundredths digit is 8 → round up → 15.3
4) 19.31 → hundredths digit is 1 → round down → 19.3
5) 3.97 → hundredths digit is 7 → round up → 4.0
6) 0.74 → hundredths digit is 4 → round down → 0.7
7) 7.016 → hundredths digit is 1 → round down → 7.0
8) 19.372 → hundredths digit is 7 → round up → 19.4
9) 90.024 → hundredths digit is 2 → round down → 90.0
10) 83.23 → hundredths digit is 3 → round down → 83.2
11) 9.567 → hundredths digit is 6 → round up → 9.6
12) 0.417 → hundredths digit is 1 → round down → 0.4

Part 3: Round to the nearest hundredth

To round to the nearest hundredth, look at the thousandths place (third digit after decimal).
- If it is 5 or more, round up the hundredths digit.
- If it is less than 5, keep the hundredths digit the same.

1) 1.174 → thousandths digit is 4 → round down → 1.17
2) 5.029 → thousandths digit is 9 → round up → 5.03
3) 0.017 → thousandths digit is 7 → round up → 0.02
4) 15.264 → thousandths digit is 4 → round down → 15.26
5) 3.996 → thousandths digit is 6 → round up → 4.00
6) 1.083 → thousandths digit is 3 → round down → 1.08
7) 24.361 → thousandths digit is 1 → round down → 24.36
8) 0.9017 → thousandths digit is 1 → round down → 0.90
9) 2.818 → thousandths digit is 8 → round up → 2.82
10) 4.617 → thousandths digit is 7 → round up → 4.62
11) 6.301 → thousandths digit is 1 → round down → 6.30
12) 0.0752 → thousandths digit is 5 → round up → 0.08
13) 1.2837 → thousandths digit is 3 → round down → 1.28
14) 8.295 → thousandths digit is 5 → round up → 8.30
15) 14.004 → thousandths digit is 4 → round down → 14.00
