is an example of a mixed number. A mixed number has a whole number part and a fraction part.
The same fraction can also be shown as an improper fraction, . This is equivalent to the mixed number, but in this case the number has been written as 5 halves. Improper fractions have numerators which are bigger than the denominators.
To convert a mixed number into an improper fraction, look at the denominator of the fraction part first. This will be the denominator of the improper fraction.
Convert into an improper fraction.
Change into halves. 3 whole ones is halves.
There is another half in the fraction part of , so altogether there are 7 halves, meaning that is the same as .
To convert any mixed number to an improper fraction:
To convert an improper fraction to a mixed number, work out how many whole numbers there are by dividing the numerator by the denominator. Make the remainder the new numerator and leave the denominator as it was.
Convert into a mixed number.
= 1 (whole one), and remainder 2.
Write as .
Mixed numbers and improper fractions are worth the same amount as one another (if they are equivalent) but are written differently. Mixed numbers are made up of a whole number and a separate fraction. Improper fractions do not show whole numbers separately and the numerator is bigger than the denominator. For example, (mixed number) is equal to (improper fraction).
