In a basketball game, you make 8 of 20 free throws. If you continue this for the next 50 free throws, how many can you expect to make?

We set up a proportion of made free throws to attempts.
8/20 = m/50 where m is the number of made free throws in 50 attempts.

We type 8/20 = m/50 into the search engine and get m = 20.
