3/14 x 8/18 x 12/20

Reduce 8/18 to 4/9 by dividing both by 2  --->  3/14 x 4/9 x 12/20

Reduce 12/20 to 3/5 by dividing both by 4  --->  3/14 x 4/9 x 3/5

The two 3's will cancel out the 9  --->  1/14 x 4/1 x 1/5

Reduce the 4 and the 14 by dividing both by 2   --->  1/7 x 2/1 x 1/5

Multiply the numerators together and the denominators together  --->  2/35
