John and Peter share some money in the ratio 2:5. If Peter gives John $60, both of them will have the same amount of money. How much money do they have altogether?

Ratio is a new topic introduced in P5. Thus it is certain that in this coming SA2, Ratio heuristic problem sums will be tested.

To make preparations easier for all P5 students, we have identified 4 commonly tested ratio concepts:

1. Identifying common base2. Before-change-after (Unchanged group)3. Before-change-after (Unchanged difference)4. Before-change-after (Unchanged total)

This week, we have developed a video on “Before-change-after (Unchanged total) “ to explain in further detail how to solve questions like the above.
