Oh, dude, that's an easy one. So, if there are 30 children in total and 60 of them are girls, you just divide 60 by 2 to get the number of girls. That's like, what, 30 girls in the class? So, yeah, there are 30 girls in the class. Easy peasy!
Well, isn't that a happy little math problem we have here? Since the boys outnumber the girls by 2 to 1, we can think of the ratio as 2 parts boys to 1 part girls. If we have 30 children in total, that means there are 20 boys and 10 girls in the class. Just imagine all those little painters creating beautiful artwork together!
estimate: is 20-30
18 girls
17. There should be 18, but one has gone to the toilet.
17/30 ( this is in its sinplest form)
Since there are 2 boys and 3 girls there are 3 girls in a class of 5. For a class of 30 there is thus 3/5 times 30 = 18 girls John

A class of 25 to 30 is considered average.
18 girls
17. There should be 18, but one has gone to the toilet.
do youmean 75 percentg are girls? Then 0.75 x 40 = 3/4 x 40 = 30 girls
17/30 ( this is in its sinplest form)
If there were 30 students in the class, it would mean that 2/5 are girls. Girls = 12. Boys = 18
15
Boys: 12/30 = 2/5 Girls: 18/30 = 3/5
there are 12 boys in the class
