Let's first simplify the expression inside the parentheses:
1/6 - 5/9 = 3/18 - 10/18 = -7/18
1/2 - 3/7 = 7/14 - 6/14 = 1/14
Now, let's multiply the simplified expressions:
(-7/18) (1/14) 7 1/5= -7/18 1/14 36/5= -7/252 * 36/5= -252/2520= -1/10
Therefore, the result of the expression is -1/10.

Now, let's multiply the simplified expressions:
(-7/18) (1/14) 7 1/5
= -7/18 1/14 36/5
= -7/252 * 36/5
= -252/2520
= -1/10
Therefore, the result of the expression is -1/10.
