On a certain legislative committee, 3/8 of the committee members are Republicans. If 2/3 of the members are men and 3/5 of the men are Democrats, what fraction of the members are Democratic women?

OpenStudy (anonymous):

1/4 of the Republicans are men?

OpenStudy (anonymous):

but 15 members are Repbulicans

OpenStudy (anonymous):

so we have 25 Democrats

OpenStudy (anonymous):

3/5 of the men are Democrats

OpenStudy (anonymous):

So, 15 of the members are men

OpenStudy (anonymous):

from the Democratic party

OpenStudy (anonymous):

so we have 25 out of 40 members to deal with

OpenStudy (anonymous):

so, 10 of the members are Republicans

OpenStudy (anonymous):

that are men

OpenStudy (anonymous):

so 5 of them most be women

OpenStudy (anonymous):

so we got 5 Republican women, 10 Republican men

OpenStudy (anonymous):

which equals 15

OpenStudy (anonymous):

and 15 more Demcratic members are men

OpenStudy (anonymous):

so we got 30

OpenStudy (anonymous):

so 10 of the democratics are women...

OpenStudy (anonymous):

but why is the answer choice 9/40?

OpenStudy (anonymous):

answer is 3/8

OpenStudy (anonymous):

what fraction of the members are Democratic women?

OpenStudy (anonymous):

15 members are Republicans, which is 15/40

OpenStudy (anonymous):

since 3/8=15/40

OpenStudy (anonymous):

Any ideas?

OpenStudy (anonymous):

so we know number of repuclican right?

OpenStudy (anonymous):

right, 15

OpenStudy (anonymous):

so we have 25 members left

OpenStudy (anonymous):

3/5 of the men are Democratics

OpenStudy (anonymous):

because it does not say in question..

OpenStudy (anonymous):

3/8 out of 40 is 15

OpenStudy (anonymous):

so we got 15 Republicans

OpenStudy (anonymous):

so we have 15 male Democratics

OpenStudy (anonymous):

where did you get 40?

OpenStudy (anonymous):

but why am I ending up with 10/40 Demo women instead of 9/40 Demo women?

OpenStudy (anonymous):

From choice B, 9/40

OpenStudy (anonymous):

3/8 can convert to 15/40

OpenStudy (anonymous):

2/3 of men are 10

OpenStudy (anonymous):

1/3 are women

OpenStudy (anonymous):

is that making sense?
