Step-by-step solution for: Roman numerals worksheets 3rd grade
To solve these problems, we need to convert Roman numerals into standard numbers (Arabic numerals).
Here is a quick guide to the symbols:
* I = 1
* V = 5
* X = 10
* L = 50
* C = 100
* D = 500
* M = 1000
Rules to remember:
1. Add them up: If a smaller number is *after* a bigger number, you add it. (Example: VI = 5 + 1 = 6)
2. Subtract them: If a smaller number is *before* a bigger number, you subtract it. (Example: IV = 5 - 1 = 4)
3. Groups: Break the numeral into chunks to make it easier. For example, in XXIV, look at XX (20) and IV (4). So, 20 + 4 = 24.
Let's solve each one step-by-step:
1. XXVIII: XX (20) + V (5) + III (3) = 28
2. LXVII: L (50) + X (10) + V (5) + II (2) = 67
3. LVII: L (50) + V (5) + II (2) = 57
4. XLI: XL (40, because 10 before 50) + I (1) = 41
5. XVII: X (10) + V (5) + II (2) = 17
6. XXX: X (10) + X (10) + X (10) = 30
7. XXIII: XX (20) + III (3) = 23
8. XLVIII: XL (40) + VIII (8) = 48
9. LXXXIV: LXXX (80) + IV (4) = 84
10. XXXVI: XXX (30) + VI (6) = 36
11. LXXX: L (50) + XXX (30) = 80
12. LX: L (50) + X (10) = 60
13. XXXV: XXX (30) + V (5) = 35
14. LXVI: LX (60) + VI (6) = 66
15. VI: V (5) + I (1) = 6
16. XXX: 30
17. XCIV: XC (90, because 10 before 100) + IV (4) = 94
18. LI: L (50) + I (1) = 51
19. XXXII: XXX (30) + II (2) = 32
20. LVIII: L (50) + VIII (8) = 58
21. VII: V (5) + II (2) = 7
22. XIX: X (10) + IX (9, because 1 before 10) = 19
23. XLV: XL (40) + V (5) = 45
24. XII: X (10) + II (2) = 12
25. X: 10
26. XI: X (10) + I (1) = 11
