It is about 12 o'clock. There are about 20 students in the class.
In my class, i have 11 classmates in another school they have 27 students, so I'm like this is too many students! Well, i believe it should have at least 15-20.
20 x 19 x 18/3 x 2 = 1,140 groups
The percentage of students in your class who are failing is 20.

The ratio of 2 / 5 is the same as 40%. We would simply take 40% of the twenty students in the class: 20 * 0.4 = 8 students have cats. (Note, this is the same as multiplying by two over five).
Here are 10 students getting honors credits in a class, and they make up 20% of the class. How do we find the number of students in the class? Let's look. We have a class, and 20% of the class are getting honors credit, and that turns out to be 10 students. Now we can generate a formula that we can use to discover our answer. Let's assign letters to the things we know or are finding out. Nclass = number of students in the class. Nhonors = number of honors students in the class. And Nhonors = 10 students. Nclass x 20% = 10 students 20% = 20/100ths (because % = hundredths) or 0.20 or just 0.2 for simplicity. Nclass x .2 = 10 students Now divide both sides by .2 so the .2 will cancel out (or drop out) on the left side of the equation and we'll have isolated the answer we are looking for, which is Nclass. Nclass = 10 students divided by .2 Nclass = 10/.2 students = 50 students There are 50 students in the class. As .2 equals 2/10 or 1/5, we can find 1/5th of 50 just by thinking about it to check our work. And 1/5th of 50 equals 10, which is in agreement with the information we were given in the problem.

If there were 30 students in the class, it would mean that 2/5 are girls. Girls = 12. Boys = 18
