Given the statement:
In a year, there are 4 months that have 30 days.
Determine the ratio of moths with 30 days to the months with other than 30 days.
Solution:
In a year there are 12 months, if 4 months have 30 days, then 8 months have either 31 days or 29 days (depending if it is leap year)
The ratio can be written as:
= 4:8
Noticed that the ratio is still divisible by 4, and by dividing 4, we can get a simplified answer.
= 1:2
Final answer: the ratio of moths with 30 days to the months with other than 30 days = 1:2
