To find out how much more it snowed yesterday than today at the Johnson Ski Resort, we have the following measurements:
- Snow yesterday: \( \frac{1}{3} \) foot
- Snow today: \( \frac{1}{6} \) foot
We need to calculate the difference:
\[ \text{Difference} = \text{Snow yesterday} - \text{Snow today} = \frac{1}{3} - \frac{1}{6} \]
To perform this subtraction, we need a common denominator. The least common multiple of 3 and 6 is 6. We will convert \( \frac{1}{3} \) to a fraction with a denominator of 6:
\[ \frac{1}{3} = \frac{2}{6} \]
Now we can substitute this back into our calculation:
\[ \text{Difference} = \frac{2}{6} - \frac{1}{6} = \frac{2 - 1}{6} = \frac{1}{6} \]
Thus, it snowed \( \frac{1}{6} \) foot more yesterday than today. The final answer is:
\[ \frac{1}{6} \text{ feet} \]
