If x is inversely proportional to y and y is directly proportional to z, then xy is : |
Directly proportional to y Inversely proportional to y Constant Directly proportional to $y^2$ |
Constant |
x is proportional to y. Therefore, x/y=a (a is a constant) y is proportional to z, so: y/z=b (b is a constant) Multiplying both the equations, we get: x/y×y/z=a×b x/z=ab (ab is a constant) |
