What is 89 in Roman numerals?

To convert the number 89 into Roman numerals, it is important to break it down into its constituent parts based on the values represented by Roman numerals. The Roman numeral system works primarily using combinations of letters from the Latin alphabet:

• L represents 50

• X represents 10

• V represents 5

• I represents 1

To represent 89, we can break it down as follows:

1. Start with the largest value less than or equal to 89, which is 80 (LXXX).

2. The number 80 in Roman numerals is represented as 8 times 10 which is denoted as LXXX (L for 50 + XXX for the three tens, which equals 30).

3. After accounting for 80, we have 9 left to account for.

4. The number 9 is represented in Roman numerals as IX (which is one less than ten).

Combining these representations, 89 is expressed in Roman numerals as LXXXIX (LXXX for 80 plus IX for 9).

Thus, the correct representation of 89 in Roman numerals is LXXXIX.
