|---|---|---|
| 50 | 3 | M1 for \(\dfrac{6}{8} \times 80\) oe (= 60) or \(\dfrac{1}{8} \times 80\) oe (= 10) (may be seen on gauges eg. 10 by \(\frac{1}{8}\) position or 60 by \(\frac{6}{8}\) position on either gauge) M1 (dep) for a complete correct method eg. “60” – “10” or 5 × “10” A1 for 50 (accept answers in the range 49 - 51) or M1 for \(\dfrac{6}{8} - \dfrac{1}{8}\) (\(= \dfrac{5}{8}\)) M1 (dep) for “\(\dfrac{5}{8}\)” × 80 A1 for 50 (accept answers in the range 49 - 51) |
