What is 48 in Roman numerals?

48 in Roman numerals is written XLVIII, combining XL (40) and VIII (8). The subtractive notation XL places X before L to indicate 10 subtracted from 50, then add VIII to reach forty-eight in standard classical form.

Why is XL used for 40 in XLVIII?

XL represents 40 because Roman numerals use subtraction: X (10) before L (50) means 50 minus 10 equals 40. In XLVIII, XL supplies forty, and the following VIII adds eight, demonstrating combined subtractive and additive rules in Roman numeral construction.

How do you convert XLVIII to Arabic numerals?

To convert XLVIII to Arabic numerals, evaluate XL as 40 (L 50 minus X 10) then add VIII: V (5) plus three I's (1+1+1) equals eight. Combine 40 and 8 to yield 48, the Arabic numeral.
