About this worksheet
Why we built it
Year 8 percentages move past "percent of" into increases, decreases and percentage error - the real-life versions students will keep using. These worksheets focus on the harder applied problems where a question first needs translating before any calculation.
What's covered
Sub-skills your student will practise
- ✓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)

From our families
Parents on the practice questions.
“Tuterly has been exactly what we needed since Tom started secondary school. Once the topic tests began, he was struggling to keep up. Now he has unlimited practice, all matched to what his class is actually covering, and his Maths results have improved noticeably.”

“My daughter used to leave revision until the night before. Having a platform she can dip into for fifteen minutes after dinner has completely changed that. She's calmer going into assessments, and honestly, so am I.”

“I like that I can just keep doing questions until it clicks. If I get something wrong, it shows me why, and then gives me another one like it.”

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.
