# Weekly Problem 49 - 2007

##### Stage: 3 and 4 Challenge Level:

The mean is $(1.\dot{2}+2.\dot{1})/2=3.\dot{3}/2=1.\dot{6}$.

Alternatively, you can convert into fractions, to get the answer of $1\frac{2}{3}$, which is the same as $1.\dot{6}$.

This problem is taken from the UKMT Mathematical Challenges.
