The method for these questions always stays the same.
Follow the process below.
y 1 x write as an inverse proportion
y = k x × k to change it into an equation
x y = k isolate k
k = 16 × 40 = 640 substitute to find the value of k
y = 640 x use the value for k in the equation.
Now you can find a value for x or y if you are given a value.
x = 10
y = 640 10
y = 64
