1) First figure out the number of days in August. This is easy because it's given to you - it's the number of days on the calendar, 31.
2) Next, count up the number of Saturdays and Sundays. There are 5 Saturdays + 5 Sundays = 10 total.
3) Finally put it as a ratio. Since you're looking for the ratio of "something" to "something," you want to put it as the first thing over the second thing (if in fraction form) or first thing:second thing.
So Saturdays and Sundays to total number of days:
[tex] \frac{10}{31} [/tex] or 10:31

Answer: [tex] \frac{10}{31} [/tex] or 10:31
