|---|---|---|---|
| \(1\frac{9}{40}\) | 3 | Mark final answer M2 for \(\dfrac{24[k] + 25[k]}{40[k]}\) or better (\(k\) is positive integer) or M1 for two equivalent fractions with common denominator of 40[\(k\)] attempted with one numerator correct If 0 scored, SC1 for answer 1.225 | Could be separate fractions M2 soi by \(\dfrac{49[k]}{40[k]}\) oe Could be seen in 2 different fractions without addition |
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| \(4.84 \times 10^4\) | 3 | M2 for figs 484 in final answer or B1 for 50 000 or \(50 \times 10^3\) seen or for 1600 or \(0.16 \times 10^4\) seen | Allow M2 if correct answer oe seen in working |
