Foundation June 2017 Paper 1 Q10
10 Work out \(\quad \dfrac{3}{8} \times 11\)
Give your answer as a mixed number. [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(\dfrac{33}{8}\) | B1 | or equivalent fraction |
| \(4\dfrac{1}{8}\) | B1ft | ft their improper fraction correctly converted to a mixed number answer only of \(4\dfrac{1}{8}\) scores B1B1 |
Additional guidance
| If their initial answer is a proper fraction they cannot access the second mark eg \(\dfrac{3}{8} \times 11 = \dfrac{33}{88}\) | B0B0ft |
| If their ft mixed number can be simplified, the simplification is not required for the second mark eg \(\dfrac{3}{8} \times 11 = \dfrac{44}{8} = 5\dfrac{4}{8}\) | B0B1ft |
| \(0.375 \times 11 = 4.125\) | B1B0 |
| \(33 \div 8\) | B0B0 |
| \(33 \div 8 = 4\dfrac{1}{8}\) | B1B1 |
| \(\dfrac{11}{8} = 1\dfrac{3}{8}\) then \(1\dfrac{3}{8} \times 3 = 3\dfrac{9}{8}\) (this gets first B1) \(= 4\dfrac{1}{8}\) | B1B1 |
