|---|---|---|
| 540 × 4 or 540 ÷ 90 × 360 oe | M1 | Candidates may work out the amount of money for each sector and sum them. This is awarded the mark provided the whole method is correct. e.g.
|
| = (£) 2160 | A1 |
| Scheme | Marks | Comments |
|---|---|---|
| \(\dfrac{120}{360}\) × 2160 oe or 540 × 4 ÷ 3 oe | M1 | FT ‘their 2160’ provided ≠ 540 Allow M1 only for 2160 × 0.33(..) unless 720 given as the answer. |
| = (£) 720 | A1 | FT |

|---|---|---|
| 0.15 × 360 oe | M1 | |

Alternative
Alternative method 1
| Scheme | Marks | Comments |
|---|---|---|
| \(\dfrac{45}{360}\) oe | M1 | |
| = 0.125 (with comparison to 0.15) | A1 |
Alternative method 2
| Scheme | Marks | Comments |
|---|---|---|
| \(\dfrac{45}{360}\) ( x 100) oe | M1 | |
| = 12.5(%)(with comparison to 15(%)) | A1 |
Alternative method 3
| Scheme | Marks | Comments |
|---|---|---|
| A method for comparing two fractions with common denominators e.g. \(\dfrac{15 \times 3.6}{100 \times 3.6}\) | M1 | |
| \(= \dfrac{54}{360}\) (with comparison to \(\dfrac{45}{360}\)) | A1 | Do not allow comparison \(\frac{1}{8}\) with \(\frac{3}{20}\). They must have a common denominator. |
