- Proper and Improper fractions. A proper fraction is one where the top is smaller than the bottom, such as When converted to a decimal, proper fraction are always less than 1. An improper fraction is the reverse, where the top is larger than the bottom, such as An improper fraction can be 'reduced'. In the example above, six quarters of a pizza is more than one pizza. In fact, if we divide the fraction to make it a decimal, or one and a half pizzas.

Fraction (mathematics) A ratio is often converted to a fraction when it is expressed as a ratio to the whole. In the above example, the ratio of yellow cars to all the cars on the lot is 4:12 or 1:3. We can convert these ratios to a fraction and say that 4/12 of the cars or ⅓ of the cars in the lot are yellow.

- Mole fraction describes the number of molecules (or moles) of one component divided by total the number of molecules (or moles) in the mixture. Mole fraction is useful when two reactive components are mixed together, as the ratio of the two components is known if the mole fraction of each is known.
