🔹 Section 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) 1.44 → Tenths digit is 4 → Less than 5 → Round down → 1
2) 6.234 → Tenths digit is 2 → Less than 5 → Round down → 6
3) 36.87 → Tenths digit is 8 → Greater than 5 → Round up → 37
4) 19.67 → Tenths digit is 6 → Greater than 5 → Round up → 20
5) 91.921 → Tenths digit is 9 → Greater than 5 → Round up → 92
6) 15.014 → Tenths digit is 0 → Less than 5 → Round down → 15

✔ Answers:
1) 1
2) 6
3) 37
4) 20
5) 92
6) 15

🔹 Section 2: Round to the nearest tenth

To round to the nearest tenth, look at the hundredths place (second digit after decimal).
- If ≥ 5 → Round up the tenths digit
- If < 5 → Keep tenths digit same

1) 45.637 → Hundredths = 3 → < 5 → Round down → 45.6
2) 9.012 → Hundredths = 1 → < 5 → Round down → 9.0
3) 15.623 → Hundredths = 2 → < 5 → Round down → 15.6
4) 9.66 → Hundredths = 6 → ≥ 5 → Round up → 9.7
5) 91.921 → Hundredths = 2 → < 5 → Round down → 91.9
6) 593.30 → Hundredths = 0 → < 5 → Round down → 593.3

✔ Answers:
1) 45.6
2) 9.0
3) 15.6
4) 9.7
5) 91.9
6) 593.3

🔹 Section 3: Round to the nearest hundredth

To round to the nearest hundredth, look at the thousandths place (third digit after decimal).
- If ≥ 5 → Round up the hundredths digit
- If < 5 → Keep hundredths digit same

1) 3.215 → Thousandths = 5 → ≥ 5 → Round up → 3.22
2) 44.444 → Thousandths = 4 → < 5 → Round down → 44.44
3) 0.009 → Thousandths = 9 → ≥ 5 → Round up → 0.01
4) 2.3838 → Thousandths = 3 → < 5 → Round down → 2.38
5) 8.005 → Thousandths = 5 → ≥ 5 → Round up → 8.01
6) 16.336 → Thousandths = 6 → ≥ 5 → Round up → 16.34

✔ Answers:
1) 3.22
2) 44.44
3) 0.01
4) 2.38
5) 8.01
6) 16.34

🔹 Section 4: Round to the nearest thousandth

To round to the nearest thousandth, look at the ten-thousandths place (fourth digit after decimal).
- If ≥ 5 → Round up the thousandths digit
- If < 5 → Keep thousandths digit same

1) 0.0091 → Ten-thousandths = 1 → < 5 → Round down → 0.009
2) 2.9999 → Ten-thousandths = 9 → ≥ 5 → Round up → 3.000
*(Note: Rounding 2.9999 up increases the thousandths place from 9 to 10, so carry over → 3.000)*
3) 0.1335 → Ten-thousandths = 5 → ≥ 5 → Round up → 0.134
4) 60.618 → Ten-thousandths = 0 → < 5 → Round down → 60.618
5) 8.1234 → Ten-thousandths = 4 → < 5 → Round down → 8.123
6) 0.196 → Ten-thousandths = 0 → < 5 → Round down → 0.196

✔ Answers:
1) 0.009
2) 3.000
3) 0.134
4) 60.618
5) 8.123
6) 0.196
