the ratio of girls to boys in the chorus is 3:2. If there are 50 students in chorus, how many boys are there and how many girls?
okay, my cousins also use my laptop for homework help. Ill just ask the questions for them.
To determine the number of boys and girls in the chorus, we need to use the given ratio and the total number of students.
Step 1: Identify the ratio given.
The ratio of girls to boys is 3:2, which means for every 3 girls, there are 2 boys.
Step 2: Determine the total number of parts in the ratio.
The total number of parts in the ratio is 3 + 2 = 5 (3 parts for the girls and 2 parts for the boys).
Step 3: Find the value of one part.
Since there are 50 students in total, each part represents 50 divided by 5 = 10 students.
Step 4: Calculate the number of girls and boys.
Multiply the value of one part by the respective parts of the ratio:
Girls: 3 parts * 10 students/part = 30 girls
Boys: 2 parts * 10 students/part = 20 boys
Therefore, there are 30 girls and 20 boys in the chorus.
Jordon, please use the same name for your posts.
3/5 = x/50
Cross multiply and solve for x.
5x = 150
x = 30 girls
