60 percent of the students in a marching band are girls. There are 30 girls in the marching band. How many students are there altogether?
Let n = total number of students.
It was said that 60% of n are girls, which is according to the problem, equal to 30. Thus,
60% * n = 30
Note that 60% is also equal to 0.6 in decimal form:
0.6 * n = 30
n = 30/0.6
n = 50 students
Hope this helps :3
60/100 = 30/x
60x = 3000
60x/60 = 3000/60
x = 50
There are 50 students.
To find the total number of students in the marching band, we can use the given information that 60 percent of the students are girls.
Let's assume the total number of students in the marching band is x.
According to the given information, 60 percent of x is equal to 30 girls.
Mathematically, this can be represented as:
0.60 * x = 30
To solve for x, we divide both sides of the equation by 0.60:
x = 30 / 0.60
x = 50
Therefore, there are 50 students in total in the marching band.
To find out how many students are in the marching band altogether, we can use the given information that 60% of the students are girls, and there are 30 girls in the band.
First, let's find the total percentage of students who are girls. Since 60% of the students are girls, this means that the remaining 40% must be boys.
To find the total number of students, we need to find 100% of the students. Since 60% represents the number of girls, we can set up the following equation:
60% = 30 girls
100% = x (total number of students)
To solve for x, we can use a proportion. We set up the equation:
(60/100) = (30/x)
To solve for x, we can cross-multiply and then divide:
60x = 30 * 100
60x = 3000
x = 3000/60
x = 50
Therefore, there are a total of 50 students in the marching band.
