M = number of months chatted to.
years = 5
5 = multiplied by 12 to equal the month.
So equation = (12x5y)/M

I would do it like this....
First think about the question.
13 months is what % of 5 years or 60 months?
second write the equation
13/12 = x times 5
or
13 = x times 60
third simplify
13 = 60x
solve
13/60 = 60x/60
21.7% = x
So 13 months is 21.7% of 5 years.
Pretty close to what NDN said! : )
Yeah, but he is a skunt. I win.
