3. Mixed numbers can be written as improper fractions:

To write a mixed number as an improper fraction,

• multiply the denominator of the proper fraction by the whole number and add the numerator of the proper fraction to your result. This gives you the numerator of the improper fraction

• carry along the denominator of the proper fraction for the denominator of the improper fraction.
