|---|---|---|
| Method for finding a percentage other than 10% or \(2100 \times 0.43\) or \(2100 \times \dfrac{43}{100}\) or \(2100 \times 43 \div 100\) or 90 300 | M1 | eg (1% =) \(2100 \div 100\) or (1% =) \(210 \div 10\) or 21 or (3% =) 63 or (5% =) \(210 \div 2\) or 105 or (20% =) \(210 \times 2\) or 420 or (40% =) \(210 \times 4\) or 840 or (50% =) \(2100 \div 2\) or (50% =) \(210 \times 5\) or 1050 |
| Fully correct method that would lead to the correct answer or \(90\,300 \div 100\) | M1dep | eg their \(21 \times 43\) or \(210 \times 4 +\) their \(21 \times 3\) or their \(420 \times 2 +\) their \(21 \times 3\) or their \(105 \times 8 +\) their \(21 \times 3\) or their 840 + their \(21 \times 3\) or their 840 + their 63 or \(210 \times 5 -\) their \(21 \times 7\) or their \(1050 -\) their \(21 \times 7\) or their \(1050 -\) their 147 |
| 903 | A1 | SC2 1197 SC1 digits 903 (with M0 scored) |
Additional guidance
| Ignore a % sign after 903 eg 903 % | M2A1 |
