At a school, three-fifths of the male students and one-half of the female students speak a foreign language. If the number of males is equal to the number of females, what fraction of the students speak a foreign language?
Choose the correct answer:
A) 11/20 B) 13/20 C) 7/10 D) 3/5 E) 2/5
Let x be the number of students in the school.   The number of males who speak a foreign language is (3/5)(1/2)x = (3/10)x   The number of females who speak a foreign language is (1/2)(1/2)x = (1/4)x   The total number of students who speak a foreign language is (3/10)x + (1/4)x = (11/20)x   The answer is 11/20.
