The ratio of 30 days in a month to 31 days in a month can be expressed as 30:31. This ratio cannot be simplified further as 30 and 31 are both prime numbers and have no common factors other than 1. This means that for every 30-day month, there is an additional 1 day in a 31-day month, making the ratio slightly less than 1:1.
