How does this quiz work?
Read each question, choose one answer among A, B, C and D, then check it: a short explanation appears after every answer. Your score out of 10 is shown at the end, and you can restart the quiz as often as you like.
What should you review before the quiz?
Reread the key facts of the lesson and the worked example. If a question is hard, go back to the matching part of the lesson, then try the quiz again. Write your work on scrap paper: most mistakes come from skipping a step, not from the idea itself.
Remember:
- To round to a place, look at the digit one place to the right.
- A digit of 5 or more rounds up. A digit of 4 or less rounds down.
- A number exactly halfway between two multiples rounds up, so 350 rounds to 400.
- All the digits to the right of the rounding place become zeros.
- Rounding 99,950 to the nearest hundred gives 100,000 because the 9 carries.
