conversations.value: Please show me the solution for: The ratio of men to women on a bus is 5:9. If the total number of passengers on the bus is 84, and 20 women alight from the bus at the next stop, how many women have remained on the bus?

conversations.value: The total ratio representing the number of women on the bus is 5+9=14
  The fraction from the ratio representing the number of women is 9/14, and since the total number of passengers representing the full ratio is 84, there are 9/14*84=54 women on the bus.
  If 20 women alight from the bus at the next stop, the number of women remaining on the bus becomes 54-20=34
