Higher November 2019 Paper 1 Q7
7 Given that \(\quad a \times 60 = b \quad\) work out the value of \(\quad \dfrac{4b}{a}\) [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(60 \times 4\) or \(4(a \times 60)\) or \(4a \times 60\) or \(\dfrac{b}{a} = 60\) or \(\dfrac{4b}{b/60}\) or \(4b = 240a\) or \(\dfrac{240a}{a}\) | M1 | accept any multiplication signs |
| 240 | A1 | Condone \(\dfrac{240}{1}\) |
Additional guidance
| Correct answer found by substituting appropriate values for \(a\) and \(b\) | M1A1 |
| Incorrect answer found by substituting appropriate values for \(a\) and \(b\) | M0A0 |
| Award M1 for \(60 \times 4\) or 240 in working, either as individual expressions or as part of longer expressions eg \(4 \times 60 = 240\), answer \(240b\) eg \(\dfrac{4 \times 60 \times a}{4b}\) | M1A0 M1A0 |
| Do not award M1 for 240 within a list of multiples of 60 that continues beyond 240 |
