Fractions are ways to represent parts of a whole. Common fractions are ½ and ¾. These are proper or regular fractions. Some fractions are called mixed numbers. These are represented by a whole number with a fraction (proper fraction). 1 ½ and 2 ¾ are good examples. An improper fraction has a larger number on the top than on the bottom‚ such as 9/8. I will explain how to convert these fractions to decimals. I will show you how to change an improper fraction to a mixed number. Operations (addition
