i am a three-digit decimal number. my thousandths is twice my tenths and my hundredths is the difference of my thousandths and tenths. what numbers am i
Let's say the number is written 0.ABC
C = 2A
B = C-A
That is only two equations in three unknowns. There could be more than one answer. A, B and C must be integers.
B = 2A - A = A
The number could be 0.112, 0.224, 0.336 or 0.448
If you say that B = A - C, there could be even more answers.
