Let x and y be the number of boys and girls in the class respectively
x + y = 24
y = (2 / 3) 24
y = 16 number of girls
=> x = 24 - 16 = 8 number of boys
therefore number of boys = 8

There are 8 boys. How do I know? Divide 24 by 3. Your answer is 8. So if 2/3 of the students are girls, that makes 2x8 = 16. The rest are boys!

Total students = 24
girls are 2/3 of 24
so, boys are 1-2/3 of 24
=(3-2)/3 of 24
=1/3 of 24
number of boys = (1*24)/3=8

24*2/3=16 girls so 24/16=8 are boys

24 students
Girls= 2/3*24 = 16
Boys = 24 - 16 = 8

Sigh . . . 24 students. 2/3 are girls so 1/3 are boys.
24 divided by . . . 3 (we are dealing with thirds so we divide by 3) equals 8. 2 (because of the 2/3) x 8 is 16 girls and 1 (because of the 1/3) x 8 is 8 boys.
Now do the rest of your own homework. Here's a great web site -- http://school.discovery.com/homeworkhelp/bjpinchbeck/ -- with lots of links to anything else that you need.

total students=24
2/3 are girls
thus 24*2/3=16
hence 16 girls
thus boys=24-16=8
that is there iare 8 boys if there are no super person
