A proper fraction is one where the numerator is smaller than the denominator. A mixed number (sometimes called a mixed fraction) has both a whole number part and a proper fraction part. An improper fraction is one where the numerator is larger than the denominator ; they are informally known as top-heavy fractions.Â
In order to carry out fraction arithmetic it is useful to be able to convert a mixed number to an improper fraction, and vice versa. For example, to convert 2 and a fifth into an improper fraction we have to write the whole number 2 in fifths. We know that 5 fifths make a whole, so 10 fifths will make 2 whole numbers. Adding 10 fifths to 1 fifth we get 11 fifths, so 2 and the mixed number 2 and a fifth is equivalent to the improper fraction of 11 fifths.Â
In order to convert an improper fraction to a mixed number we need to divide the numerator by the denominator. For example, to convert 7 quarters from an improper fraction to a mixed number, we need to divide 7 by 4. 4 goes into 7 once leaving a remainder of 3 quarters. So the improper fraction of 7 quarters is equivalent to the mixed number 1 and 3 quarters.
Looking forward, students can then progress to additional number worksheets, for example a percentage worksheet or a rounding worksheet.
