|---|---|---|
| \((16.4 - 3.92 =)\) 12.48 or \((16.4 + 7.8 =)\) 24.2 or \((7.8 - 3.92 =)\) 3.88 | B1 | |
| 20.28 | B1ft | ft their \(12.48 + 7.8\) or their \(24.2 - 3.92\) or their \(3.88 + 16.4\) SC1 4.68 |
Additional guidance
| Answer of 20.28 | B1B1 |
| 4.68 comes from \(16.4 - (3.92 + 7.8)\) | SC1 |
| \(-4.68\) | SC0 |
| Follow through must have at least 1 decimal place eg \(16.4 - 3.92 = 12\) then \(12 + 7.8 = 19.8\) eg \(16.4 - 3.92 = 12.58\) then \(12.58 + 7.8 = 20.38\) | B0B0ft B0B1ft |

| 406.23 | B2 | Ignore further work e.g rounding B1 \(400 \leqslant\) answer \(< 410\) B1 digits 40 623 (not 406.23) |
Additional guidance
| 0406.23 | B2 |
| Ignore trailing zeros eg 406.230000 | B2 |
| 406.23 in division calculation and 406 on answer line | B2 |
| 406.23 in division calculation and 46.23 on answer line cannot be considered a transcription error and cannot be ignored as further work | B1 |
