boys : girls = 3 : 4 means that there are 3x boys and 4x girls in the class. So we have:
3x + 4x = 42
7x = 42
7x/7 = 42/7
x = 6
3x = 3(6) = 18 (the number of boys)
4x = 4(6) = 24 (the number of girls)
Thus, there are 24 girls in the class.
21 boys + 14 girls = 35 studentsThis also works for math and social studies classes.
There are 1007 girls and 901 boys.
Oh, dude, let me break it down for you. So, if you have 17 girls and 10 boys in the class, the probability of selecting a girl is like the number of girls divided by the total number of students. So, it's 17 girls out of 27 students, which simplifies to about 63%. Cool, right?
Girls + girls = silly (as well).
ya they can well I guess some boys can be stronger than a girl and if your one of those girls I hope your smart! girls are usally smarter than boys and defently prettier!

a class of 25 students has 10 boys. Three boys have braces and 4 girls have braces..what is the ratio of boys with braces to boys in class
The ratio is 94:141
Oh, dude, you're hitting me with the math questions now? Alright, let me break it down for you. So, there are 28 boys and 14 girls in the class, right? That means there are a total of 42 pupils. To find the fraction of girls, you just divide the number of girls by the total number of pupils. So, 14 girls out of 42 pupils gives you a fraction of 1/3. Easy peasy, lemon squeezy.
