This table shows the numbers of students in different classes that are in the math club.
Students in math club
Boys / Girls
Mrs.Smith 3 / 4
Ms.Jones 4 / 6
Mr.Brown 3 / 4
a. What fraction of the students in the math club are boys from Mrs. Smithâ€™s class?
b. What fraction of the students in the math club are girls?
c. Some more girls joined the math club, but no more boys joined. The number of girls in the math club is now 23 of the total number of members. How many more girls joined the math club? Show your work or explain how you know.

3/7
7+10+7 = 24 total students
14 are girls
so
14/24 = 7/12
suspect you mean 2/3 are girls
(14+x) /(24+x) = 2/3
42 + 3 x = 48 + 2x
x = 6 more girlsposted by Damon

a. is actually 3 / 24 because if I recall the problem says what fraction of the students in the math club are boys from Mrs.Smith class.So won't it be Mrs.Smith boys to all of the class.

Rodger is right

c. there was 14 girls to start with so wouldn't you subtract 14 from 23 and get 9.

I think you added 6 girls and get 20 out of 30

oh, I assumed that the 23 was a typo and it meant 2/3
