Divide the number of girls by the total number of children (boys + girls).
There are 12 boys.
boys : girls = 3 : 4 means that there are 3x boys and 4x girls in the class. So we have:3x + 4x = 427x = 427x/7 = 42/7x = 63x = 3(6) = 18 (the number of boys)4x = 4(6) = 24 (the number of girls)Thus, there are 24 girls in the class.
1 to 2 = 5 to 10 so 15 students in all.
the number of girls in a class compares to color of bananas
10:18 or 5:9 (simplified)
The probability is the number of girls divided by the number of students, so 12/22, or 6/11
18 boys and 12 girls
It is 8 : 26.
There are 18 girls and 6 boys in the class of 24 students
Let the number of boys in class X = a, The number of girls will be a+3, Let the number of boys in class X = a, The number of girls will be a+3, The total number of students is a+a+3=11 2a+3=11 2a=11-3 2a=8 a=8/2 a=4 Therefore, the number of boys is 4, the number of girls will be 4+3 which will be 7. Please let me know if you understand. Thanks.
45 boys are in the class
yes there is difftrent class for boys and girls
5 to 4
Divide by 9 (4 + 5), then multiply by either 4 or 5 to get the first number. Subtract that number from the total to get the second number. Multiply the quotient from the first step by the other number (4 or 5) to check the second answer.
20 girls are in the class.
21 to 14
The girls are 100% of the females and the boys are 100% of the males
