9 Work out \(\quad 25.68 \div 12\) [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| Alternative method 1 | ||
| 2.14 | B2 | oe B1 answer of 2.1(……) except 2.14 B1 0.214 or 21.4 or 214 or 2140 |
| Alternative method 2 | ||
| Divides by 2, 2 and 3 in any order or divides by 3 and 4 in either order or divides by 2 and 6 in either order | M1 | oe Attempts at all divisions must be made using a valid method |
| 2.14 | A1 | oe |
Additional guidance
| \(25.68 \div 2 = 12.84\) \(25.68 \div 3 = 8.56\) \(25.68 \div 4 = 6.42\) \(25.68 \div 6 = 4.28\) | |
| Use of remainders is B0 eg \(\;25.68 \div 12 = 2\) remainder 1.68 | B0B0 |
| Do not accept rounding up to 26 or 30 or truncation to 25 eg \(\;26 \div 12 = 2.1666\ldots\) | B0B0 |
| \(2\dfrac{7}{50}\) (possibly from multiplying numerator and denominator by 1000 and cancelling the subsequent fraction) | B2 |
