In Jessica's art class, the ratio of girls to boys is 3:2. If there are 25 students in the class, how many more girls are there than boys?
Girls : Boys = 3 : 2
3x = girls
2x = boys
3x + 2x = 25
5x = 25
x = 5
Girls = 3x = 3(5) = 15
Boys = 2x = 2(5) = 10
How many more girls are there than boys?
20
5 boys
To find the number of girls and boys in Jessica's art class, we need to determine the ratio of students for each gender.
Given that the ratio of girls to boys is 3:2, we can assume that the class can be divided into 5 equal parts (3 parts for girls and 2 parts for boys).
To find the size of each part, we can divide the total number of students by 5:
25 students / 5 parts = 5 students per part
Now, we can calculate the number of girls and boys:
Girls: 3 parts x 5 students per part = 15 girls
Boys: 2 parts x 5 students per part = 10 boys
To find the difference between the number of girls and boys, subtract the number of boys from the number of girls:
15 girls - 10 boys = 5 more girls than boys
Therefore, there are 5 more girls than boys in Jessica's art class.
