What are the common mistakes in Inverse proportion?

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.

• Treats an inversely proportional relationship as if it were directly proportional

  Scaled the time the same way as the quantity changed (as if this were direct proportion) instead of using the inverse relationship

• Attempts to answer a proportion question without first finding the constant of proportionality k

  Divided the given time (12) by the new number of identical machines (3) directly, instead of first finding $k = 4 \times 12 = 48$ and then dividing k by the new quantity

• Takes the reciprocal incorrectly when finding the constant k for an inverse proportion relationship

  Found k as $\frac{y}{x}$
