Question

How do rates help you describe real life problem? Give two example

Answer 1

A rate allows us to compare two numbers or measurements and give them a value. This helps us in real life to make everyday activities simpler. For example: you have to take a photocopy as quickly as possible and you have two photocopiers. The first draws 10 copies per minute and the second only 5 copies per minute. Using the rates you can know that the first option in better because you will have the double of copies in the same time.  Another example is a place where you get 2 pizzas for $10 and another where you get 1 for $8. The rates help you to know that in the first place they give you 1 pizza for $5 (10÷2=5) so it is a cheaper option.
