Substitute each of the letters by a different decimal digit from 1 to 9 to satisfy this cryptarithmetic equation:
A/(B*C) + D/(E*F) + G/(H*I)
= 1
A/(B*C) + D/(E*F) + G/(H*I)
= 1

The formula is (x/y) + (x/z) = 1, where x is any one digit number and y and z are the factors of x.
No, this formula only works for one digit numbers since it requires dividing by the product of the number's factors.
This formula demonstrates inverse operations by showing that dividing by a number's factors and then adding those factors back together results in the original number.
Yes, there are a few exceptions where the formula does not hold true such as 0/0 or 1/1. These cases would result in undefined or infinite values.
This formula can be used in various mathematical and scientific calculations, such as finding missing numbers in a sequence or solving for unknown variables in equations.
