In a class,1/2 of the male students and 2/3 of the female students speak Frenc. If there are 3/4 as many girls as boys,what fraction of the entire class speaks Frenc?

Let  the  number of boys  = B

Then  the number of girls  = (3/4)B

 

(1/2)  of the  boys = (1/2)B

(2/3)  of the girls  =(2/3)(3/4)B  = (1/2) B

 

So  the fraction  that speak French   =

 

B [ 1/2 + 1/2 ]                 1

____________  =     ______  =      4 / 7

B [ 1  +  3/4 ]               (7/4)
