Answer
$\frac{18}{35}$
Work Step by Step
$\frac{108}{210}$
Now write the numerator and denominator as a product of prime factors.
108 = $2\times2\times3\times3\times3$
210=$2\times3\times5\times7$
$\frac{108}{210}$
=$\frac{2\times2\times3\times3\times3}{2\times3\times5\times7}$
=$\frac{1\times2\times1\times3\times3}{1\times1\times5\times7}$
=$\frac{18}{35}$
