5 x 6 x 7 x 3 = 630
14x49x15x6 = 61740

so it's 630/61740 then simplify it:

63/6174 = 7/686 = 1/98

the answer is 1/98:

5/15 = 1/3, 6/6=1, 7/49=1/7 so until now we can write:
1/14*1/7*1/3*3/1
1/3*3/1=1 ==> there just remains: 1/14*1/7= 1/98

5/14 x 6/49 x 7/15 x 3/6
= (5 x 6 x 7 x 3)/(14 x 49 x 15 x 6)
= 5/15 x 6/6 x 7/14 x 3/49
= 1/3 x 1 x 1/2 x 3/49
= 1/3 x 1/2 x 3/49
= 1/6 x 3/49
= 1/2 x 1/49
= 1/98
