To find the decimal that represents the number of girls in the drama club, first we need to determine the total number of girls in the club. Given that there are 20 students in total and 4 of them are boys, we can find the number of girls by subtracting the number of boys from the total number of students.
Here are the steps:
Step 1: Find the number of girls in the drama club
Number of girls = Total number of students - Number of boys
Number of girls = 20 - 4
Number of girls = 16
Step 2: Express the number of girls as a fraction of the total student count
The fraction representing the girls is girls/total students, so we have:
Fraction of girls = Number of girls / Total number of students
Fraction of girls = 16 / 20
Step 3: Convert the fraction into decimal form
To convert this fraction into a decimal, we divide the numerator by the denominator:
Decimal form = 16 ÷ 20
Decimal form = 0.8
Therefore, the decimal that represents the number of girls in the drama club is 0.8.
