Grade 8 & 9 Fractions, Decimals and Percentages
Fix the holes in your foundations now — before high school maths exposes them.
If fractions still trip you up, every Grade 10 algebra question is going to feel ten times harder than it needs to. Spend a week here and you'll thank yourself for the next four years.
Why most learners find this hard
Schools rush past fractions in primary school. The gaps don't show up until algebra mixes fractions and variables in Grade 10.
What you'll learn
- Adding and subtracting fractions with different denominators
- Multiplying and dividing fractions
- Converting fractions ↔ decimals ↔ percentages
- Percentage increase, decrease, and reverse percentages
- Mixed-number arithmetic without a calculator
Worked example
What is 2/3 + 1/4 as a single fraction?
- 1Find a common denominator. LCM of 3 and 4 is 12.
- 2Convert: 2/3 = 8/12 and 1/4 = 3/12
- 3Add: 8/12 + 3/12 = 11/12
Answer: 11/12
Exam tips
- When in doubt, convert everything to the same form (all fractions, or all decimals).
- Reverse percentages: divide, don't multiply, by the percentage factor.
- Mental shortcuts: 50% = ÷2, 25% = ÷4, 10% = ÷10. Stack them for trickier values.
