The fourth proportional of 24, 32 and 36 is:
48
The correct answer is 48.
In our problem, 32 \times 36 = 24 \times 48, which is 1152 = 1152, confirming our answer is correct. Another important concept is the mean proportional (or geometric mean). For two numbers a and c, the mean proportional b is such that a:b = b:c, or b^2 = ac. This means b = \sqrt{ac}.
