How to Convert 72 into Roman Numerals
Roman numerals are made up of seven letters: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). To write a number like 72, we combine these letters starting from the largest value and working down to the smallest.
Let's break 72 into parts and build the Roman numeral step by step:
50 fits into what's left of the number one time.
That means we add L to our Roman numeral because one × fifty equals 50.
10 fits into what's left of the number two times.
That means we add XX to our Roman numeral because two × ten equals 20.
1 fits into what's left of the number two times.
That means we add II to our Roman numeral because two × one equals 2.
Final Answer
After combining all the parts, the Roman numeral for 72 is:
LXXII
Tip: If a smaller numeral appears before a larger one (like IV), it means you subtract. If a smaller one comes after a larger one (like VI), it means you add. You'll see both styles when needed.
How to Convert the Roman Numeral LXXII into a Normal Number
To convert a Roman numeral to a normal number, we read it from left to right and add up the values of each symbol. However, if a smaller symbol appears before a larger one, we subtract the smaller value instead of adding it.
Let's break down LXXII step by step:
Step 1: We see L, which means we add fifty (add 50).
Step 2: We see X, which means we add ten (add 10).
Step 3: We see X, which means we add ten (add 10).
Step 4: We see I, which means we add one (add 1).
Step 5: We see I, which means we add one (add 1).
Total calculation: L (50) + X (10) + X (10) + I (1) + I (1) = 72
Final Answer
The normal number for the Roman numeral LXXII is:
72
Tip: Remember the key rule - if a smaller numeral appears before a larger one (like IV), subtract the smaller value. If a smaller one comes after a larger one (like VI), add the values together.
