Exercise 2 Page 546

A ratio is a comparison of two quantities by division. We can write a ratio of two numbers a and b, where b ≠ 0, in three ways. a/b a : b a to b We are given the following measurements. Number of open spots:& 15 Number of competing girls:& 30 We want to find the ratio of open spots to the number of competing girls. 15/30 Finally, we can write the ratio as a fraction in simplest form.
