George is building a fence. he builds his fence at a constant rate of 1/3 section of fence every 1/2 hour. at this rate, which fraction represents the section of fence george can build per hour? enter your answer as a fraction. (type as a decimal, round to the hundredths place)

Fraction of fence = 2/3 which is approximately 0.67

Explanation:
We know that he finishes 1/3 of the fence in 1/2 an hour. To know the fraction he can finish in one hour, we will simply use cross multiplication as follows:
1/3 of the fence > 1/2 an hour
?? of the fence > 1 hour
Fraction of the fence = (1/3 * 1) / (1/2)
Fraction of fence = 2/3 which is approximately 0.67

Hope this helps :)
