How to Write and Convert Numbers to Roman Numerals (1–399)
FAQs on Roman Numerals Practice Worksheet for Class 4 (1–399)
1. What are the basic rules for writing Roman numerals?
The basic rules for writing Roman numerals involve combining symbols like I, V, X, L, and C. For Class 4 Maths, the key rules to remember are addition and subtraction.
- Addition Rule: When a symbol of a smaller value is written after a symbol of a larger value, their values are added. For example, VI = 5 + 1 = 6.
- Subtraction Rule: When a symbol of a smaller value (only I, X, or C) is written before a symbol of a larger value, the smaller value is subtracted. For example, IV = 5 - 1 = 4.
- Repetition Rule: A symbol can be repeated up to three times in a row. For example, III = 3 and XXX = 30. The symbols V, L, and D are never repeated.
2. How do you write 399 in Roman numerals?
To write 399 in Roman numerals, you break the number down by place value and convert each part. This is a key exercise in the roman numerals 1-399 topic.
- Hundreds place (300): This is written as CCC (100 + 100 + 100).
- Tens place (90): This is written using the subtraction rule as XC (100 - 10).
