Enigma 1582 - Bit tricky

ENIGMA 1582 — Bit tricky

by Bob Walker

Joe thought he would test Penny's ability to manipulate equations this week. So he asked her to find the values of the integers A, B and C in the following equation.

(A.B + 1)

(A.B.C + A + C)

0.138

What are the values of A, B and C?

I (DH) think that it is quite easy to find a solution, but am not sure that it is the only one.
