How many adults are waiting in line?</h3>
Ratio expresses the relationship between two or more numbers. Ratio is used to compare two or more numbers. It shows the number of times that one value is contained in another value.
Looking at the ratio given in this question, we know that there are 1 1/2 (3 /2) more children than adults on the line to watch the new superhero movie.
Number of adults waiting to see the movie = (ratio that represents adults / sum of ratio) x total number of people wafting in line
Sum of ratios = 2 + 3 = 5
(2/5) x 155 = 62 people
