Find the third proportion of 8,24, ? 60

To find the third proportion, we use the formula for the proportion of four quantities, which is: a : b = c : d. Here, a and b are the first two quantities, c is the third quantity, and d is the fourth quantity we want to find.

Given a = 8, b = 24, and c = 60, we can substitute these values into the formula:

8 : 24 = 60 : d

To solve for d, we cross-multiply:

8 * d = 24 * 60

Solving for d gives:

d = (24 * 60) / 8

d = 180

So, the third proportion of 8, 24, and 60 is 180.
