A new superhero movie has its first showing and there are 155 people in line to see it. If the ratio of kids to adults waiting to see this movie is 3:2 , how many adults are in line? Use a tape diagram to help organize your thinking.(1 point) adults

Answer 1

To solve this problem, we can start by representing the number of kids and adults in line using a tape diagram.

Let's represent kids with "K" and adults with "A".

The ratio of kids to adults waiting to see the movie is 3:2, which means that for every 3 kids, there are 2 adults.

We can represent this ratio using the tape diagram below:

K K K | A A

Now, we know that there are a total of 155 people in line. To find the number of adults, we need to determine how many groups of 2 adults are in line.

Since each group of 3 kids is accompanied by 2 adults, we can divide the total number of people in line by 3 (to find how many groups of kids there are) and then multiply that number by 2 (to find how many groups of adults there are).

155 / 3 = 51.67 (approximately)

Since we can't have a fraction of a group, we need to round down to the nearest whole number. Therefore, there are 51 groups of kids.

Now, to find the number of adults in line, we multiply the number of groups of adults by the number of adults in each group:

51 * 2 = 102

Therefore, there are 102 adults in line to see the superhero movie.
