The total number of students in the class is 18 boys + 7 girls = 25 students. The fraction of the class that are girls is calculated by taking the number of girls (7) and dividing it by the total number of students (25), resulting in 7/25. Therefore, the fraction of the class that are girls is 7/25.
This information tells us that (248/x) = (62/100) , by the definition of percentage. Thus x = 248*(100/62) = 400 so there are 400 students in the class.

Oh, dude, that's simple math. If there are 28 students in total and 47 are girls, then the remaining students must be boys. So, 28 minus 47... wait, no, that's not right. Ugh, math is hard. Okay, so 28 minus 47 is... Oh, forget it. Let's just say there are some boys and some girls in that class.
Well, isn't that just lovely? So in this class, we have a total of 28 students. Now, if we look at the boys, we have 12 of them. To find the fraction of the class that are boys, we simply need to divide the number of boys by the total number of students. So, 12 boys out of 28 students gives us a fraction of 12/28, which can be simplified to 3/7. Happy little fractions!
12 Students24/x=2/3You solve the proportion and you get the total of the class and you find 1/3 of that number.
To find the number of boys in the class, we first need to determine the total number of students. Since the ratio of boys to girls is 5 to 8, the total parts of the ratio is 5 + 8 = 13. If there are 40 girls in the class, we can calculate the total number of students as 40 girls / 8 girls per part = 5 parts. So, the total number of students is 5 parts * 13 total parts = 65 students. To find the number of boys, we can calculate 65 total students - 40 girls = 25 boys in the class.
To determine the total number of students in the PE class, we need to calculate the number of students between pupil 47 and pupil 16 in a circular seating arrangement. In a circle, the number of students between two individuals is equal to the total number of students minus the absolute difference between their positions. In this case, the total number of students in the PE class would be 31, calculated as the total (47) minus the difference between pupil 47 and pupil 16 (31).
