Converting Mixed Numbers to Improper Fractions
Converting mixed numbers to improper fractions takes
two steps:
1. Multiply the whole number by the denominator.
2. Add this product to the numerator.
IF necessary, you must reduce your mixed number.
Example:
Mixed Number: 2 4/8
Step One: 2 * 8 = 16 (Multiply whole by denominator)
Step Two: 16 + 4 = 20 (Add product and numerator)
Improper Fraction: 20/8

4).
