|---|---|---|
| Correct conversion to a comparable form \(\left(\dfrac{31}{40} =\right)\) 0.775 or \(\left(\dfrac{3}{4} =\right)\) \(\dfrac{30}{40}\) or 0.75 or \(\left(\dfrac{7}{10} =\right)\) \(\dfrac{28}{40}\) or 0.7 or (0.725 =) \(\dfrac{29}{40}\) or any two of 77.5(%), 75(%), 70(%), 72.5(%) | M1 | |
| \(\dfrac{7}{10}\) 0.725 \(\dfrac{3}{4}\) \(\dfrac{31}{40}\) with no incorrect working | A1 | oe accept in converted form |
Additional guidance
| Two correct conversions using fractions with common denominators other than 40 eg \(\dfrac{124}{160}\) and \(\dfrac{120}{160}\) | M1 |
| Correct order with incorrect working \(\dfrac{31}{40} = 0.925\), \(\dfrac{3}{4} = 0.75\), \(\dfrac{7}{10} = 0.7\) \(\dfrac{7}{10}\), 0.725, \(\dfrac{3}{4}\), \(\dfrac{31}{40}\) | M1A0 |
