Answer:
9 inches per year
Step-by-step explanation:
We are told that in a 3/12 year period, the amount of snowfall was 27/12. Therefore, we can find the amount of snowfall in one year by using the following proportion:
[tex]\frac{3}{12}:\frac{27}{12}=\frac{12}{12}:x[/tex]
where 12/12 represents one year, and x the amount of snowfall in one year. Solving for x, we find
[tex]x=\frac{\frac{27}{12}\cdot \frac{12}{12}}{\frac{3}{12}}=\frac{\frac{27}{12}}{\frac{3}{12}}=\frac{27}{3}=9[/tex]
So, the average yearly snowfall is 9 inches per year.
