Comparing numerators without accounting for different denominators.

Guardrail: Do not copy official questions, invent a fixed test length or weighting, ignore units, round too early, infer score from difficulty or rely on returning to an earlier item.

Memory anchors

Common form first

Compare fractions, decimals or percentages in one consistent form.

Fraction of amount

Divide by the denominator, then multiply by the numerator.

Equivalent means same value

Multiplying top and bottom equally preserves the fraction.

Decimal conversion

Numerator divided by denominator.

Sense-check the fraction

A proper fraction of a positive amount should be smaller than the whole.

Checkpoint rule

Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Knowledge Check (after reading)
