Worked examples
On a number line marked from 0 to 1,000 with intervals of 100, which point is closest to 720?
- Halfway between 700 and 800
- Just past 700
- Halfway between 600 and 700
- Just before 800
Answer: Just past 700. 720 is 20 past 700 — closer to 700 than to 750 (the halfway point between 700 and 800).
A car costs £8,400. Roughly how much does a school need for 4 cars?
- About £32,000
- About £40,000
- About £8,400
- About £3,200
Answer: About £32,000. £8,400 ≈ £8,000; 4 × £8,000 = £32,000.
A pupil writes: 'The number 3,250 rounded to the nearest 1,000 is 3,000.' A teacher marks this wrong. Why?
- The hundreds digit is 2, but the next digit (5 in tens of hundreds, i.e. the hundreds column) is 2 — actually 3,250 to the nearest 1,000 IS 3,000. The teacher is wrong.
- Should be 4,000.
- Should be 3,300.
- Should be 2,000.
Answer: The hundreds digit is 2, but the next digit (5 in tens of hundreds, i.e. the hundreds column) is 2 — actually 3,250 to the nearest 1,000 IS 3,000. The teacher is wrong.. Look at hundreds digit (2). 2 < 5 → round down. 3,250 → 3,000. Pupil is right.
