| 20 | 3 | M1 for \(330 \div 120\) (= 2.75) or \(200 \div 60\) (= \(3\tfrac{1}{3}\)) or \(450 \div 180\) (= 2.5) M1 for \(450 \div 180\) (= 2.5) AND \(8 \times \text{``}2.5\text{''}\) (= 20) A1 cao OR M1 for \(120 \div 8\) (= 15) or \(60 \div 8\) (= 7.5) or \(180 \div 8\) (= 22.5) M1 for \(330 \div (120 \div 8)\) (= 22) or \(200 \div (60 \div 8)\) (= 26.6...) or \(450 \div (180 \div 8)\) (= 20) A1 cao OR M1 for multiples of 120:60:180, eg 240:120:360 M1 for multiples linked to 450 and 8+8+4 or scaling 2.5 oe A1 cao |
