Rounding Decimal Places - Rounding numbers to 2dp - Free Printable

Let's solve each part of this rounding worksheet step by step and explain the rules used.

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 point):
- If it’s 5 or more, round up.
- If it’s less than 5, round down.

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

Part 2: Round to the nearest tenth

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

#### Answers:
1) 4.83 → 4.8 (hundredths = 3 < 5 → keep 8)
2) 1.94 → 1.9 (hundredths = 4 < 5 → keep 9)
3) 15.28 → 15.3 (hundredths = 8 ≥ 5 → round up 2→3)
4) 19.31 → 19.3 (hundredths = 1 < 5 → keep 3)
5) 3.97 → 4.0 (hundredths = 7 ≥ 5 → round up 9→10, so 3.9 → 4.0)
6) 0.74 → 0.7 (hundredths = 4 < 5 → keep 7)
7) 7.016 → 7.0 (hundredths = 1 < 5 → keep 0)
8) 19.372 → 19.4 (hundredths = 7 ≥ 5 → round up 3→4)
9) 90.024 → 90.0 (hundredths = 2 < 5 → keep 0)
10) 83.23 → 83.2 (hundredths = 3 < 5 → keep 2)
11) 9.567 → 9.6 (hundredths = 6 ≥ 5 → round up 5→6)
12) 0.417 → 0.4 (hundredths = 1 < 5 → keep 4)

Part 3: Round to 2 decimal places (2dp)

To round to 2 decimal places, look at the thousandths place (third digit after decimal):
- If it’s 5 or more, round the hundredths digit up.
- If it’s less than 5, keep the hundredths digit same.

#### Answers:
1) 1.174 → 1.17 (thousandths = 4 < 5 → keep 7)
2) 5.029 → 5.03 (thousandths = 9 ≥ 5 → round up 2→3)
3) 0.017 → 0.02 (thousandths = 7 ≥ 5 → round up 1→2)
4) 15.264 → 15.26 (thousandths = 4 < 5 → keep 6)
5) 3.996 → 4.00 (thousandths = 6 ≥ 5 → round up 9→10, carry over: 3.99 → 4.00)
6) 1.083 → 1.08 (thousandths = 3 < 5 → keep 8)
7) 24.361 → 24.36 (thousandths = 1 < 5 → keep 6)
8) 0.9017 → 0.90 (thousandths = 1 < 5 → keep 0)
9) 2.818 → 2.82 (thousandths = 8 ≥ 5 → round up 1→2)
10) 4.617 → 4.62 (thousandths = 7 ≥ 5 → round up 1→2)
11) 6.301 → 6.30 (thousandths = 1 < 5 → keep 0)
12) 0.0752 → 0.08 (thousandths = 5 → round up 7→8)
13) 1.2837 → 1.28 (thousandths = 3 < 5 → keep 8)
14) 8.295 → 8.30 (thousandths = 5 → round up 9→10, carry over: 8.29 → 8.30)
15) 14.004 → 14.00 (thousandths = 4 < 5 → keep 0)
