Mixed Numbers & Improper Fractions

Here is how to convert from a mixed number to an improper fraction and vice versa:

Example 1

Example 1

  • Convert 73\dfrac{7}{3} to a mixed number.
    • First, find how many times the denominator fits as a whole, then write the remainder as a fraction.
    • Then, simplify the whole number part and combine.
Example 2

Example 2

  • Convert 3123\dfrac{1}{2} to an improper fraction
    • First, multiply the whole number (3$$) by a fraction equal to 1 using the denominator ($$\dfrac{2}{2}).
    • Then add the remaining fraction.
    • Finally, multiply and add the fractions.
