Number: fractions, decimals, percents and ratios: key rules to remember

Ontario Curriculum, Number strand (Grades 3–8 B; Grade 9 B)
- Place value and decimals; ordering decimals (more digits does not mean larger).
- Fractions: equivalent fractions, operations; dividing by a fraction = multiplying by its reciprocal.
- Percents, fraction–decimal–percent equivalence (1/8 = 0.125 = 12.5 %).
- Integers and rational numbers on a number line.
- Powers, square roots (√50 between 7 and 8), scientific notation (first factor 1 ≤ a < 10).
- Factors and multiples: GCF, LCM.
- Proportional reasoning: unit rates, ratios, percent change on different bases.
- Common misconceptions used as distractors: adding numerators and denominators; counting decimal places; additive instead of multiplicative reasoning.
