Answer 1

Answer:

"12" (and any subsequent words) was ignored because we limit queries to 32 words.

Answer 2

Answer:

1. The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
