How to Convert from Improper to Mixed Fractions
QuestionConvert the mixed fraction below to an improper fraction.
Multiply the whole number (2) by the denominator of the fraction (2).
2 × 2 = 4
Take this answer (4) and add the numerator (1) of the fraction part of the mixed fraction.
4 + 1 = 5
Make this the numerator of the improper fraction.
Take the denominator from the fraction part of the mixed fraction (2) and make this the denominator of the improper fraction.
Simplify the fraction if possible. (The fraction in our example is already as simple as possible).
Answer:5/2 (five-halves) is 2 1/2 (two and a half) written as a mixed fraction.
