Example questions from this paper
A preview of the wording. The answer options and full explanations appear once you begin.
- The bar chart shows the attendance at a club on four days. On which day does the attendance round to 60 to the nearest 10?
- A shop sells 48 books at £9.85 each. Estimate the total takings.
- A ribbon is 1.847 m long. How long is this to the nearest 10 cm?
- A table is 1.4 m long, measured to the nearest 10 cm. What is the shortest it could be?
- A number rounds to 250 when rounded to the nearest 10. Which of these CANNOT be the number?
Before you begin, remember
- 5 or more rounds up, 4 or less rounds down. Watch for 9s: rounding 3,297 to the nearest ten gives 3,300, not 3,290.
- In an estimation question, round every number first and only then calculate. Working it out exactly and rounding at the end wastes the time the question is trying to save you.
