A mixed number is a combination of a whole number and a fraction. For example, if you have two whole apples and one half apple, you could describe this as 2 + 1/2 apples, or 21/2 apples.Writing Mixed Numbers as FractionsThis mixed number can also be expressed as a fraction. Each whole apple contains two half apples. Your two whole apples are also four half apples. Four half apples plus one half apple is five half apples. So you have 5/2 apples.To put this another way: to turn a mixed number into a fraction, multiply the whole number by the denominator (the bottom part), and add the result to the numerator (the top part).21/2 = ?
  Multiply the whole number by the denominator.
    The whole number is 2.
    The denominator is 2.
    2 x 2 = 4.
  Add the result to the numerator:
    The numerator is 1.
    4 + 1 = 5
  The numerator is 5. The denominator remains 2.
21/2 = 5/2
Another ExampleLet's try another example:52/3 = ?
  Multiply the whole number by the denominator.
    The whole number is 5.
    The denominator is 3.
    5 x 3 = 15.
  Add the result to the numerator:
    The numerator is 2.
    15 + 2 = 17
  The numerator is 17. The denominator remains 3.
52/3 = 17/3
