Problema Solution
Three-fifths of the passengers on a cruise are female. Half of the female passengers and one-third of the male passengers are Canadian. What fraction of the passengers are Canadian?
Answer provided by our tutors
suppose total = x
3/5 x = female so 2/5 x = male
1/2*3/5 + 1/3*2/5 = canadian
3/10 + 2/15
9/30 + 4/30
13/30 are canadian
ratio is 13 : 30
