| Question 40[2 marks] | |
|---|---|
| Answer or working | Marks |
| identifying that the first significant figure is the hundreds digit, 1, and all following digits become 0 for 1 sf | B1 |
| correct reasoning that the next digit (4, the tens digit) is less than 5, so the 1 is not rounded up, giving 100; 150 is not a rounding to 1 significant figure | B1 |
| Final answer: 100, because the first significant figure (1) is followed by a 4, which is less than 5, so it rounds down; 150 has two significant figures, not one. | |
