| 10, 11, 13, 14, 16, 17 | B1 | cao |
| Answer | Mark | Mark scheme |
|---|---|---|
| \(\dfrac{5}{9}\) | M1 | for identification of 10, 12, 14, 15, 18 or for \(\dfrac{a}{9}\) where \(1 \leqslant a \leqslant 8\), \(a\) an integer, or \(\dfrac{5}{b}\) where \(b > 5\), \(b\) an integer or for incorrect form, eg 5 : 9 |
