Arithmetic - Fractions

Please select a resource from the list below.

Quick Reference

  • Fractions involving symbols occur frequently. It is necessary to be able to add and subtract them. On this leaflet, we revise how these processes are carried out. An understanding of writing fractions in equivalent forms is necessary.
  • This leaflet reminds students how to express a fraction in its simplest form, and how to add, subtract, multiply and divide fractions.
  • The ability to work confidently with fractions, both number fractions and algebraic fractions, is an essential skill which underpins all other algebraic processes. In this leaflet, we remind yo uof how number fractions are simplified, added, subtracted, multiplied and divided.
  • Fractions involving symbols occur frequently. It is necessary to be able to multiply and divide them. On this leaflet we revise how these processes are carried out.
  • This leaflet explains how algebraic fractions can be simplified by cancelling common factors.

Teach Yourself

  • In this unit we shall see how to add and subtract fractions. We shall also see how to add and subtract mixed fractions by turning them into improper fractions.
  • What are fractions? Fractions are ways of writing parts of whole numbers. For example if we take a pizza, and divide it up equally between 4 people, each person will have 1/4 or, written in words, one quarter of the pizza.
  • In this unit we shall see how to multiply fractions. We shall also see how to divide fractions by turning the second fraction upside down.

These videos require Windows Media Player (v10).

Please note: You may experience trouble with more recent upgrades to Internet Explorer (now v.7) and Media Player (now v.11). These no longer support streaming from the mms servers used by mathcentre, so we are recommending that you uninstall IE7 (IE6 lies underneath) and replace the new version of WMP with the fully functioning v.10 (you may need to find a download via google after uninstalling v.11). All those that have done this have reported back that everything is working again.
