Since the variables are inversely proportional, the proportion [tex]\frac{2}{6} = \frac{5}{h}[/tex] cannot be used to determine the number of hours it will take 5 people to build the swing set.
The rule of three is:
2 people - 6 hours
5 people - h hours
Considering that the measures are inversely proportional, for the proportion, one of the fractions has to be inverted, hence, it should be:
[tex]\frac{2}{6} = \frac{h}{5}[/tex]
