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. (Engineering Maths First Aid Kit 1.1)
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 you how number fractions are simplified, added, subtracted, multiplied and divided.
Multiplication And Division
