| Answer | Mark | Comments |
|---|---|---|
| \(\dfrac{7}{5}\) or \(1\dfrac{2}{5}\) | B2 | B1 28 and 20 |
| or \(2\dfrac{1}{3}\) and \(1\dfrac{2}{3}\) oe mixed numbers or fractions with common denominator | ||
| or correct unsimplified fraction or mixed number eg \(\dfrac{14}{10}\) or \(1\dfrac{8}{20}\) | ||
| or correct simplification of a fraction where at least one of the values is 28 or 20 and the other is not 12 | ||
| SC1 \(\dfrac{5}{7}\) |
Additional guidance
| Allow a fractional numerator and/or denominator in a correct fraction eg \(\dfrac{2\frac{1}{3}}{1\frac{8}{12}}\) or \(\dfrac{\frac{28}{12}}{\frac{5}{3}}\) | B1 |
| \(\dfrac{2.4}{1.8}\) simplified to \(\dfrac{4}{3}\) | B0 |
| Ignore an attempt to convert \(\dfrac{7}{5}\) to a mixed number eg \(\dfrac{7}{5} = 1\dfrac{2}{7}\) on the answer line | B2 |
| 7 : 5 with no working worthy of B1 | B0 |
