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!
boys:girls::7:9
A) The ratio of the number of girls to the number of boys is 260:240, which simplifies to 13:12. B) The total number of pupils in the school is 240 boys + 260 girls = 500 pupils. Therefore, the ratio of the number of boys to the total number of pupils is 240:500, which simplifies to 12:25.
45 boys are in the class
The ratio of girls to boys in the class can be calculated by dividing the number of girls by the number of boys. With 15 girls and 10 boys, the ratio is 15:10. This can be simplified to 3:2 by dividing both numbers by their greatest common divisor, which is 5. Thus, the ratio of girls to boys is 3:2.
The ratio of girls to boys in Charlotte's class is 3:2. This is found by dividing the number of girls by the number of boys to get 21/14 = 3/2.
There are 12 boys.

The ratio is: 2 to 1
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
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.
The ratio is 94:141
