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
3/14 x 8/18 x 12/20
