An example of a proportional question is, if I know 10% of Mileyworld is 500m2, how large is Mileyworld? To work this out, we say:
This is a fraction. We can thus cross-multiply. we therefore know that . Therefore, . Thus, .
This is the best method to do this question. You can alternatively think in your logic, if 10% is , therefore 1% is . Thus, 100% would be .
