The numbers of girls in the choir is 4 times the number of boys in the choir .the

First, make up some variables to represent the number of Girls and Boys in the choir.  

B = number of boys
G = number of girls

You know that there are 4 times as many girls in the choir as boys.  Therefore, the equation you can write is:


If you cross-multiply, then you get the simplified equation:
G = 4B

Intuitively this makes sense since if you multiplied the number of boys in the class by 4, that would be equal to the number of girls you have.

Now, we know that the total class size is 60. So girls plus boys equals 60:
G+B = 60

To solve the equation, replace the G in this equation with the replacement you found before, 4B.
G + B = 60 -->
4B + B = 60 -->
5B = 60 -->
B = 12

However, you are trying to find the number of girls, so plug the answer back into your equation.
G + B = 60 -->
G + 12 = 60 -->
G + 12 -12 = 60 - 12 -->
G = 48

The number of girls you have is 48.

Hello!

If School ends in June 2, and know that school start's like in Aug 10, then that means that we would have like around " 98 days" of SUMMER BREAK!

By the way, did you know that

Some critics of summer vacation point out that American students spend approximately 180 days (26 weeks) per year in school, but Asian students are "in school for 240 to 250 days"!!!.

Amazing right!?

Anyways, Hope I Helped! Have A Wonderful Day! :)
