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.

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.

boys/girls =b/g =3/1 so b=3g
and b+g=236
4g=236 so g = 59 and b= 177

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

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.
