Counterintuitive, but true.
Here's one way to look at it: if we know that 17 out of 25 apples are red, and we have 100 apples total, we can set up a proportion to find out how many red apples we would expect to have:
17/25 = x/100
Solving for x (the number of red apples in a sample of 100), we get:
x = (17 * 100) / 25 = 68
This means we'd expect approximately 68 red apples in a sample of 100 apples, maintaining the same proportion.
Working with Different Numerators and Denominators
The principles used for 17 out of 25 apply to other ratios as well. To convert any ratio "a out of b" to a percentage, follow these steps:
