Roman numerals worksheet for translating and writing numbers.

Let's solve the Roman numeral worksheet step by step.

Part 1: Translate these Roman numerals.

We’ll convert each Roman numeral to its Arabic (standard) number.

#### Basic Roman Numeral Values:
- I = 1
- V = 5
- X = 10
- L = 50
- C = 100
- D = 500
- M = 1000

Rules:
- When a smaller numeral appears before a larger one, it is subtracted.
- Otherwise, values are added.

Now let’s translate:

1. XII
X = 10, I = 1, I = 1 → 10 + 1 + 1 = 12

2. XXIX
XX = 20, IX = 9 (since I before X means 10 - 1 = 9) → 20 + 9 = 29

3. XLVI
XL = 40 (X before L = 50 - 10 = 40), VI = 6 → 40 + 6 = 46

4. LII
L = 50, II = 2 → 50 + 2 = 52

5. LXXI
L = 50, XX = 20, I = 1 → 50 + 20 + 1 = 71

6. LXVI
L = 50, X = 10, V = 5, I = 1 → 50 + 10 + 5 + 1 = 66

7. LXXX
L = 50, XXX = 30 → 50 + 30 = 80

8. XCIII
XC = 90 (X before C = 100 - 10 = 90), III = 3 → 90 + 3 = 93

9. VII
V = 5, II = 2 → 5 + 2 = 7

10. C
C = 100

✔ Part 1 Answers:
- XII → 12
- XXIX → 29
- XLVI → 46
- LII → 52
- LXXI → 71
- LXVI → 66
- LXXX → 80
- XCIII → 93
- VII → 7
- C → 100

Part 2: Write these numbers in Roman numerals.

We’ll convert each Arabic number into Roman numerals.

1. 37
30 = XXX, 7 = VII → XXXVII

2. 98
90 = XC, 8 = VIII → XCVIII

3. 64
60 = LX, 4 = IV → LXIV

4. 19
10 = X, 9 = IX → XIX

5. 23
20 = XX, 3 = III → XXIII

6. 45
40 = XL, 5 = V → XLV

7. 51
50 = L, 1 = I → LI

8. 74
70 = LXX, 4 = IV → LXXIV

9. 88
80 = LXXX, 8 = VIII → LXXXVIII

10. 5
→ V
