| Answer | Mark | Mark scheme |
|---|---|---|
| \(\dfrac{95}{28}\) | M1 | for a method to add using common denominators with at least one fraction correct (matching numerator with common denominator) eg \(\dfrac{60}{28} + \dfrac{35}{28}\) or \((2)\dfrac{4}{28} + (1)\dfrac{7}{28}\) |
| A1 | \(\dfrac{95}{28}\) oe eg \(3\dfrac{11}{28}\) |
