About this lesson and its coverage
Original Kidemy Class 6 progression. This level has its own text, examples and questions. Curriculum versions share the progression; complete board-specific coverage still needs specification matching and additional material.
Learn the idea
A ratio records an order. Add its parts before sharing a total. A unit rate compares an amount with one unit of another quantity. State units so that the rate can be used meaningfully.
Worked example
Share 35 in ratio 2:5: one part=5, shares10 and 25. If4 pens cost48 taka, each costs12 taka.
- Identify the quantities and restrictions.
