| \(8.96 \times 1540 \div 1000\) | M2 | M1 for \(8.96 \times 1540\ (= 13798.4)\) Allow M1 for digits \(896 \times 1540\) if incorrect mass unit conversion seen first |
| = 14 (kg) | A2 | A1 for 13.7(98…) or 13.8 (kg) FT from M1 to award: A2 for an answer of 14000 Allow A2 for a correct FT answer with 14 as the only non-zero digits from a seen incorrect unit conversion A1 for an answer of 13798(.4) or 13800 Allow A1 for either of the following:
a number with only non-zero digits of 896 × a number with only non-zero digits of 154 e.g. \(0.0896 \times 1.54\) |
