47 in Roman Numerals = XLVII
Forty-seven is written XLVII in Roman numerals. The subtractive rule works once in XLVII, in XL for 40: a smaller glyph placed before a larger one is taken away rather than added, which keeps XLVII shorter than stacking strokes would.

Frequently asked questions
How do you write 47 in Roman numerals?
Write 47 as XLVII, combining XL + V + I + I. Start from the largest value that fits and work down until nothing is left over.
Why is 47 not written XXXXVII?
XLVII uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. XXXXVII breaks that rule, which is why XLVII is the only correct form.
Which Super Bowl is XLVII?
Super Bowl XLVII is the 47th Super Bowl, played in 2013. The NFL sets its championship number in Roman numerals, which is why so many people look up values like XLVII.
Is there a shorter way to write 47?
No. XLVII is the standard, canonical spelling. Each value has exactly one correct Roman form, so XLVII is the only valid way to write 47.
