if 3/5 of the class are boys and there are 12 more boys than girls. How many girls are there in the class?
3/5-2/5=1/5
So proportion is
1/5 of the class equals 12 students
So the whole class is 5*12=60 students.
# of Girls = 60*2/5=24
3 *12 = 36
5*12 = 60
60-36 = 24
To find the number of girls in the class, we can follow these steps:
Step 1: Let's assume the total number of students in the class is represented by "x".
Step 2: As given, 3/5 of the class are boys. So, the number of boys in the class is (3/5) * x.
Step 3: It is also mentioned that there are 12 more boys than girls. So, the number of girls in the class would be (3/5) * x - 12.
Hence, the number of girls in the class is (3/5) * x - 12.
