What are the common mistakes in Writing one quantity as a fraction of another?

When a pupil makes one of these on Revision Workshop, the marking engine names the mistake and explains it, instead of just marking the answer wrong.

• Divides a total in the wrong ratio proportion (e.g. splits equally instead of by given ratio)

  Wrote the roses as a fraction of the tulips (12:16) instead of as a fraction of the total number of plants (28)

• Averages two percentages calculated separately instead of combining the underlying raw marks over the combined totals, which only coincides with averaging when the totals are equal

  Finds each paper's percentage separately (55% and 75%) and averages them to get 65%, or a similar shortcut, instead of correctly combining the raw marks (33+75) over the raw totals (60+100) - this only matches the correct answer when both papers are worth the same total.

• Averages two percentages directly instead of combining the raw marks over the combined totals to get the correct weighted overall percentage

  Averages 85% and 76% directly ((85+76)/2 = 80.5%) instead of combining the raw marks (17+19) out of the combined total (20+25) to get the correct weighted overall percentage.
