Let’s solve the Roman numerals worksheet step by step.

Part 1: Write the correct number next to each Roman numeral.

We’ll use the table provided (which shows values for 1s, 10s, and 100s) and standard Roman numeral rules:

- I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000
- When a smaller numeral comes before a larger one, subtract it (e.g., IV = 4, IX = 9).
- Otherwise, add them up.

Let’s go one by one:

1) CC → C=100, so 100 + 100 = 200

2) CL → C=100, L=50 → 100 + 50 = 150

3) CDV → CD = 400 (because C before D means 500 - 100), then V=5 → 400 + 5 = 405

4) DLX → D=500, L=50, X=10 → 500 + 50 + 10 = 560

5) CML → CM = 900 (M=1000, C before M → 1000 - 100), L=50 → 900 + 50 = 950

6) CXXV → C=100, XX=20, V=5 → 100 + 20 + 5 = 125

7) DLVI → D=500, L=50, V=5, I=1 → 500 + 50 + 5 + 1 = 556

8) CXC → XC = 90 (X before C → 100 - 10), plus C at start? Wait — let’s break it down:
C = 100, XC = 90 → but actually, CXC is C + XC = 100 + 90 = 190

Wait — double-check: CXC → first C (100), then XC (90) → yes, 190. Correct.

9) DCCX → D=500, CC=200, X=10 → 500+200+10 = 710

10) DLXXII → D=500, L=50, XX=20, II=2 → 500+50+20+2 = 572

11) CLXXIX → C=100, LXX=70, IX=9 → 100+70+9 = 179

12) DCCLXX → D=500, CC=200, LXX=70 → 500+200+70 = 770

13) CMXXXVII → CM=900, XXX=30, VII=7 → 900+30+7 = 937

14) DCLXXXIV → D=500, CLXXX=180 (C=100, LXXX=80), IV=4 → 500+180+4 = 684

✔ All Part 1 answers checked.

Part 2: Write the correct Roman numerals next to each number.

We convert numbers using place value and the chart.

1) 150 → 100 (C) + 50 (L) → CL

2) 320 → 300 (CCC) + 20 (XX) → CCCXX

3) 615 → 500 (D) + 100 (C) + 10 (X) + 5 (V) → DCXV

Wait — 615 = 600 + 15 → DC (600) + XV (15) → DCXV

4) 94 → 90 (XC) + 4 (IV) → XCIV

5) 412 → 400 (CD) + 10 (X) + 2 (II) → CDXII

6) 541 → 500 (D) + 40 (XL) + 1 (I) → DXLI

7) 225 → 200 (CC) + 20 (XX) + 5 (V) → CCXXV

8) 532 → 500 (D) + 30 (XXX) + 2 (II) → DXXXII

9) 809 → 800 (DCCC) + 9 (IX) → DCCCIX

10) 674 → 600 (DC) + 70 (LXX) + 4 (IV) → DCLXXIV

11) 298 → 200 (CC) + 90 (XC) + 8 (VIII) → CCXCVIII

12) 943 → 900 (CM) + 40 (XL) + 3 (III) → CMXLIII

13) 477 → 400 (CD) + 70 (LXX) + 7 (VII) → CDLXXVII

14) 839 → 800 (DCCC) + 30 (XXX) + 9 (IX) → DCCCXXXIX

✔ All Part 2 answers verified.
