Start with the mixed number 1 2/3. The whole number is 1, the numerator is 2, and the denominator is 3. Multiply the whole number by the denominator: 1 × 3 = 3. Then add the numerator: 3 + 2 = 5. Keep the same denominator, 3. So the improper fraction is 5/3. This conversion works because one whole equals 3/3, and 3/3 plus 2/3 gives 5/3.

You can also confirm the answer by thinking of the mixed number as one whole and two more thirds. One whole is 3/3, and adding 2/3 makes 5/3. That shows the fraction is greater than 1, which matches the original mixed number. Since the denominator stays 3, only the numerator changes after combining the whole number and the fraction. The final form is still the same value, just written as an improper fraction.
