| Answer | Mark | Comments |
|---|---|---|
| Alternative method 1 | ||
| \(70 \times 2.2\) or 154 | M1 | |
| their 154 \(\div\) 14 or \(11 \times 14 = 154\) | M1dep | \(70 \times 2.2 \div 14\) oe is M1M1dep |
| 11 | A1 | |
| Alternative method 2 | ||
| \(14 \div 2.2\) or 6.36… or 6.4 or \(2.2 \div 14\) or 0.157... or 0.16 | M1 | |
| 70 \(\div\) their 6.36 or 70 \(\times\) their 0.157 or 11.006... or 10.9375 or 10.99 | M1dep | |
| 11 | A1 | |
Additional guidance
| \(14 \div 2.2 = 6.3\) and \(70 \div 6.3 = 11.1\) | M1M1depA0 |
| Only \(70 \div 6.3 = 11.1\) | M0M0depA0 |
| Only \(70 \div 6.4\) (= 10.9375) | M1M1depA0 |
| eg 10.9375 \(\to\) answer 11 | M1M1dep A1 |
| Only \(70 \div 14\) or 5 | M0 |
| \(70 \div 14 = 5\) and \(5 \times 2.2\) | M1M1dep |
| \(70 \times 2.2 = 154,\ 154 \div 14 = 11,\ 11 \times 70 \quad\) Answer 770 (11 seen) | M1M1depA0 |
| \(70 \times 2.2 = 154,\ 154 \div 14 \times 70 \quad\) Answer 770 | M1M0depA0 |
