6 divide n = 9 and 5 over 6

What numbers have no recrpricol?

The product of 7 over 12 and a mystery number is 1 over 2. What is the number?

Can anyone help mee?

Zero has no reciprocal. The reciprocal of 1 is 1. The reciprocal of 1 is 1.
If 7x/12 = 1/2, then
12 = 14x
x = 6/7
I did the first one in a different post
