| 2 squares shaded | 1 | B1 cao |
| Answer | Mark | Notes |
|---|---|---|
| 150 | 2 | M1 \(200 \div 4 \times 3\) or \(0.75 \times 200\) oe A1 cao |
| Answer | Mark | Notes |
|---|---|---|
| Explanation | 2 | C2 for a full explanation, eg answer given as \(\tfrac{4}{35}\) or “He subtracted \(\tfrac{3}{5}\) from a fraction less than 1 so the answer must be less than 1” (C1 for a partial explanation, eg use of a suitable common denominator or “He should have used a common denominator”) |
