Welcome to the second of our Easy quizzes on Rounding Numbers. This is all about making approximations which make your estimated answers much closer to the real answer.
Here’s an example:
If you want to know what 48 x 12 is then you might round the numbers to 50 x 10. This makes your estimated answer 500. The real answer should be a similar amount. In fact, 48 x 12 = 576.
To round numbers just ask yourself which ten, hundred or thousand they are nearest to. But don’t forget the rule: 5s, 50s and 500s are always rounded UP not DOWN.
Okay then, are you ready? Let’s begin the quiz. See if you can get all ten questions right.
