Do not quite understand, very weak on total unchanged concepts question, because you need to find the Common factor to make them equal, but thank you, I know it must make it whole numbers, so cannot have decimal numbers, thank you

Try to digest, 36 is totally concept wrong for that total unchanged Qn.

This rate question is again based on total unchanged.
