At a school, three-fifths of the male students and two-thirds of the female students speak a foreign language. If the number of males is two-thirds the number of females, what fraction of the students speak a foreign language?  Choose the correct choice from the following answers
A) 11/25	B) 14/25	C) 16/25	D) 18/25	E) 21/25
Let x be the number of students in the school.   The number of males who speak a foreign language is (3/5)(2/5)x = (6/25)x   The number of females who speak a foreign language is (2/3)(3/5)x = (2/5)x   The total number of students who speak a foreign language is (6/25)x + (2/5)x = (16/25)x   The answer is 16/25.
