If twenty percent of the students play in the band and the band has forty members, how many students are there?
Please help me
0.2x = 40
x = 40/0.2
x = 200
To find the total number of students, you can use the concept of proportions.
Step 1: Let's assume the total number of students as 'x'.
Step 2: Given that 20% of the students play in the band, we can write it as:
20% of x = 40
Step 3: To convert 20% to a decimal, divide it by 100:
(20/100) of x = 40
Step 4: Simplify the left side of the equation:
0.2x = 40
Step 5: To solve for x, divide both sides of the equation by 0.2:
0.2x / 0.2 = 40 / 0.2
This gives us:
x = 200
Therefore, there are 200 students in total.
