12 Put these numbers in order from smallest to largest.
\[8 \times 10^{-4} \qquad 4 \times 10^{-2} \qquad 6 \times 10^{-4} \qquad 0.07\][2 marks]
| Answer | Mark | Comments |
|---|---|---|
| One correct conversion to a comparable form \(0.08 \times 10^{-2}\) or 0.0008 \(400 \times 10^{-4}\) or 0.04 \(0.06 \times 10^{-2}\) or 0.0006 \(7 \times 10^{-2}\) or \(700 \times 10^{-4}\) | M1 | |
| \(6 \times 10^{-4}\) \(8 \times 10^{-4}\) \(4 \times 10^{-2}\) 0.07 with no clearly incorrect working | A1 | oe accept in converted form |
Additional guidance
| Correct answer from clearly incorrect working | A0 |
| Accept numbers with two decimal points if it is clear that the point has been moved to the correct place eg 0.0008.0 with curved lines between each place value between the decimal points | |
| If the numbers are converted into fractions, at least two must be given correctly with common denominators to score the first mark | |
| eg \(\dfrac{4}{100}\) and \(\dfrac{7}{100}\) | M1 |
| eg \(\dfrac{6}{1000}\) and \(\dfrac{8}{1000}\) only | M0 |
| eg \(\dfrac{6}{10\,000}\) and \(\dfrac{7}{100}\) only | M0 |
