Convert the mixed number 4 1/3 into an improper fraction.

Explanation:
To convert a mixed number to an improper fraction, multiply the whole-number part by the denominator and then add the numerator, keeping the same denominator. For 4 1/3, 4 × 3 = 12, and 12 + 1 = 13, so the improper fraction is 13/3. This matches the original mixed number because 13 ÷ 3 equals 4 with remainder 1. The other options don’t fit: 12/3 equals 4 (missing the extra 1/3), 4/3 equals 1 1/3, and 16/3 equals 5 1/3.
