Find the mean proportional between 48 and 12.

To find the mean proportional between two numbers, you use the formula for the geometric mean. The geometric mean of two numbers, a and b, is the square root of their product.

Here are the steps to find the mean proportional between 48 and 12:

Step 1: Multiply the two numbers together. 48 * 12 = 576

Step 2: Take the square root of the product. The square root of 576 is 24.

So, the mean proportional between 48 and 12 is 24.
