Percentage Problems

Percentage Problems in NSW Year 8 maths (NESA outcome MA4‑FRC‑C‑01) brings the topic together in questions with several steps. The key step is deciding which quantity is 100%, because in a two-step problem the whole often changes partway through.

You will find a part, write a part as a percentage and find a whole, then combine them: the votes left for a third candidate, a percentage of a percentage, a retainer plus commission, a pay rise per fortnight and the number of weeks needed to save for a phone. Election counts, a muesli bar’s sugar, a family budget and a bushfire in a national park are all covered. It is part of Year 8 Fractions and Percentages.
