Fractions, Decimals and Percentages
Move accurately among common numerical representations and relative changes.
Prepare the abilities, not a supposed replica
Develop transferable reasoning, visual response, concentration and multitasking skills, then follow the instructions presented during the official assessment.
Core concepts
Concept 1
Move accurately among common numerical representations and relative changes.
Exam cue: Identify the active rule and reference frame before acting.
Concept 2
Estimate first, then use a short calculation and check the result's magnitude.
Exam cue: Balance pace with a repeatable accuracy check.
Concept 3
Use original exercises to build transferable aptitude rather than memorising supposed live-test content.
Exam cue: Treat the exercise as general ability practice, not a reconstruction of the RAF interface.
Risk pitfalls and guardrails
Percentage-point change and percentage change are not interchangeable.
Guardrail: Do not turn a broad public ability into a claim about secure RAF test content.
Do not infer secure CBAT timing, scoring or task design from this practice topic.
Guardrail: Do not turn a broad public ability into a claim about secure RAF test content.
Memory anchors
Fractions, Decimals and Percentages: focus
Move accurately among common numerical representations and relative changes.
Fractions, Decimals and Percentages: method
Estimate first, then use a short calculation and check the result's magnitude.
Fractions, Decimals and Percentages: boundary
This original study topic supports the public RAF ability “Numerical reasoning”; it is not a disclosed CBAT subtest or live item format.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
