I need help with a math problem that i dont really understand.... help(problem below)?

for every girl taking classes at the martial arts school, there are 3 boys who are taking classes at that school. If there are 236 students taking classes, write and solve a proportion to predict the number of boys taking classes at the school.

If 3/4 (75%) of the whole school is made up of boys then the answer is 1 : 177.
Reply:boys/girls =b/g =3/1 so b=3g


and b+g=236


4g=236 so g = 59 and b= 177
Reply:236 * 3/4 =





177
Reply:My guess is 236 divided by 4 (1 girl to 3 boys)


That equals 59. Now multiply 59 by 3 (to get the number of boys)


The answer is 177.
Reply:4 over 1= 236 over 1





4=236


there are 59 girls and 177 guyz
Reply:Let g = # of girls


Let 3g = # of boys





g + 3g = 236


4g = 236


Divide both sides by 4.


g = 59


3g = 177





There are 177 boys.
Reply:the wording might get confusing, but if you write out the variables you are going to use it makes these types of problems a lot easier :D.





g=girls


b=boys


t= total students





ok, now that we have defined variables lets see what data we have to work with:





g=g


b=3g


t=236





lets just use one variable so that it makes the equation easier to handle, we will use g.





so the equation is:


g+3g=236





add like terms:


4g=236





divide each side by 4 to find g:


g=59





59 girls


3x59= 177 boys





enjoy and good luck
