At Springfield High, three-fourths of the male students and one-half 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?
I attempted this question but every time I get B. the OA is E
my approach was choosing a number, in this case I chose 120 as the total students, and solved it from there.
can anyone please help
Consider total students = 120
given, M = (2/3)F
so F= 72 and M = 48
3/4M +1/2F speak foreign language = (3/4)* 48 + (1/2)*72 = 36+36 = 72
ratio = 72/120 = 3/5
