GCSE Maths Practice: inverse-proportion

Question 7 of 10

Find y using inverse proportion formula.

‹ ›

\( \begin{array}{l} \text{y is inversely proportional to x.} \\ \text{When x = 4, y = 18.} \\ \text{Find y when x = 6.} \end{array} \)

Choose one option:

\( \text{10} \) \( \text{12} \) \( \text{14} \) \( \text{16} \)

Inverse proportion: y = k / x, solve for k first, then divide by new x.
