State the units of your answer. [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(9.5 \times 100\) or 950 or \(20 \div 100\) or 0.2 or \(2 \times 20 \div 100\) or 0.4 | M1 | oe 930 implies 950 9.3 implies 0.2 |
| their \(950 - 2 \times 20\) or their \(950 - 40\) or 910 or \(9.5 - 2 \times\) their 0.2 or \(9.5 -\) their 0.4 or 9.1 | M1dep | oe eg \(950 - 20 - 20\) oe eg \(9.5 -\) their \(0.2 -\) their 0.2 |
| 910 cm or 9.1 m | A1 | oe |
Additional guidance
| Up to M2 may be awarded for correct work, with no answer or incorrect answer, even if this is seen amongst multiple attempts | |
| 9 m 10 cm on answer line | M1M1A1 |
| Units may be seen in working but must be seen with the correct value eg 910 on answer line with 910 cm seen in working | M1M1A1 |
| \(9.5 - 2 \times 20 = 910\) centimetres or 9.1 metres | M1M1A1 |
| \(9.5 - 2 \times 20 = 910\) or 9.1 | M1M1A0 |
| Do not ignore further incorrect conversion after correct answer seen eg 910 cm = 91 m | M1M1A0 |
