PSLE Maths - Solve All Ratio Questions

[@sarahc760]

Hi Benjamin, can you help with this question. If A gives 12 sweets to B, they will have equal amount. If B gives 12 sweets to A, their ratio will be 5:2. This is a total unchanged question, but it seems like it requires a cross method to solve the question. Why is that so? Thanks so much for your help.

The question you asked does not require using the cross method. Instead use the total unchanged method.
