Fill in the missing number. Inverse proportion: as one quantity grows, the other shrinks. The product of both stays the same.

3 × 8 = 6 × ?
What does this generator do?
The generator gives you a simple inverse proportion: two values in the top row and one in the bottom. Find the fourth so that the product of both pairs is the same.
How to solve it
First multiply the two values in the top row — that gives you the constant product. Then divide that product by the known number in the bottom row — the result is the missing value.
