Foundation November 2017 Paper 1 Q6
6
(a) Work out \(\qquad 9174 \div 11\) [2 marks]
(b) Work out \(\qquad \dfrac{5}{6} + \dfrac{3}{7}\)
Give your answer as a mixed number. [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| Division set up, with 8 and a remainder 3 seen in correct position or \(830 \leqslant\) answer \(< 840\) but not 834 | M1 |  |
| 834 | A1 |
Additional guidance
Build up method or chunking method must lead to \(830 \leqslant\) answer \(< 840\) to score M1 or better
| Answer | Mark | Comments |
|---|---|---|
| \(\dfrac{35}{42}\) (+) \(\dfrac{18}{42}\) | M1 | oe fractions with a correct common denominator and at least one correct numerator |
| \(\dfrac{53}{42}\) | A1 | oe improper fraction |
| \(1\dfrac{11}{42}\) | B1ft | oe mixed number ft for correct conversion of an improper fraction to a mixed number |
Additional guidance
| For B1ft the mixed number must not be an integer | |
| Beware \(5 + 3 = 53\) | M0 |
| When attempts are made to cancel the fraction, full marks cannot be scored \(\dfrac{53}{42} = \dfrac{9}{4} = 2\dfrac{1}{4}\) (attempt to cancel occurs before conversion to mixed number) \(\dfrac{53}{42} = 1\dfrac{11}{42} = 1\dfrac{1}{3}\) (attempt to cancel occurs after completely correct answer seen) | M1A1B0 M1A1B0 |
