#### Answer

$\frac{1}{6}$ or 1:6

#### Work Step by Step

Convert both measurements to inches.
The height of a table tennis net is 6 in.
The height of a tennis net is 3 ft = 36 in. (remember there are 12 inches in a foot)
This gives you the proportion $\frac{6}{36}$.
Simplifying by dividing the numerator and denominator by 6 gives you $\frac{1}{6}.$
The proportion can either be written as $\frac{1}{6}$ or 1:6
