Question

Rewrite the following numbers in ascending order:
XIX, XXI, XIV

• A. XIV, XIX, XXI
• B. XIX, XXI, XIV
• C. XIV, XXI, XIX
• D. XIX, XXI XIV

Answer 1

The correct option is A XIV, XIX, XXI

When a Roman numeral with the larger value is on the left, we add the values together and when it is on the right, we subtract the values.

$\therefore$XIX = 10 + 10 - 1 = 19
XXI = 10 + 10 + 1 = 21
XIV = 10 + 5 - 1 = 14

We know that 14 < 19 < 21.
So, when we arrange these numbers in ascending order, we get:
XIV, XIX, XXI
