Must know

1Ratio compares quantities, proportion states equality of ratios, and unitary method finds one unit before scaling.
2Keep quantities in the same unit, simplify the ratio, or find the value of one unit first.
3A ratio must compare quantities in the same unit.
4Write value of 1 unit clearly before multiplying.

Formula / process

1Ratio, Proportion, and Unitary Method questions become easier when the representation and rule are chosen before...
2Keep diagrams, signs, units, and final statements visible.
3Percentage Introduction questions become easier when the representation and rule are chosen before calculating.
4Profit, Loss, and Simple Interest questions become easier when the representation and rule are chosen before...

Exam traps

1Students often skip the one-unit step.
2Write value of 1 unit clearly before multiplying.
3If 4 pens cost Rs 80, what is cost of 1 pen?
4Students sometimes treat percent as a whole number.

Answer frame

Start with the exact keyword or formula before adding explanation.
Use one example, diagram cue, observation, or substitution to support the answer.
For 3 marks: definition, reason, and one supporting point.
For 5 marks: setup, method/process, example, conclusion, and final check.

ModelPercentage Introduction

Percentage Introduction model

Percentage means a tion/out of 100 and can be converted to tions/or decimals.

Given

The values, diagram, expression, or data from the question.

Rule

Write percent as denominator 100, then simplify or convert.

Check: Show the representation before the calculation.

Plain tokens, blank price cards, shop counter model, and blank timeline strip showing profit, loss, and simple interest.

ModelProfit, Loss, and Simple Interest

Profit, Loss, and Simple Interest model

Profit, loss, and simple interest use percentage to compare money changes.

Given

The values, diagram, expression, or data from the question.

Rule

Use profit = SP - CP, loss = CP - SP, and SI = (P x R x T)/100.

Check: Show the representation before the calculation.
