- ✓Percentage increase and decrease
- ✓Reverse-percentage problems (find the original price)
- ✓GST (add or extract from a total)
- ✓Percentage error in measurement
- ✓Real-world problems (sales, mark-ups, commission)

Frequently asked
Questions parents ask about percentages
What's a percentage increase or decrease?
An increase or decrease expressed as a percentage of the original. A $50 item raised to $60 is a $10 increase, which is 10/50 = 20% of the original. The formula is (change / original) x 100.
How do students do a reverse percentage problem?
If $60 is the new price after a 20% increase, divide by 1.2 to get back to the original ($50). For a 20% decrease, divide by 0.8. The 'multiplier' approach saves a lot of working.
What's percentage error?
How far off a measurement or estimate is from the true value, as a percentage. Formula: (|measured - actual| / actual) x 100. Year 8 introduces this for measurement contexts.
Is GST a Year 8 topic?
Yes - Year 8 uses 10% GST in financial contexts. Students learn both directions: adding GST (multiply by 1.1) and extracting GST from a total (divide by 1.1).
Want a real plan for the term?
Worksheets are great for repetition. A Tuterly tutor can spot the specific moves your student keeps getting wrong and fix them in one or two sessions.
