You gave me 5 digits. -- The first digit can be any one of the 5 digits. For each one, -- The second digit can be any one of the remaining 4 digits. For each one, -- The third digit can be any one of the remaining 3 digits. For each one, -- The fourth digit can be any one of the remaining 2 digits. For each one, -- The fifth digit can only be the remaining 1 digit. So there are (5 x 4 x 3 x 2 x 1) = 120 possible different arrangements.
The first can be any one of 10 digits. For each of those . . .The second can be any one of the nine digits not the same as the first. For each of those . . .The third can be any one of the nine digits not the same as the second. For each of those . . .The fourth can be any one of the nine digits not the same as the third. For each of those . . .The fifth can be any one of the nine digits not the same as the fourth. For each of those . . .The sixth can be any one of the nine digits not the same as the fifth. For each of those . . .The seventh can be any one of the nine digits not the same as the sixth. For each of those . . .The eighth can be any one of the nine digits not the same as the seventh. For each of those . . .The ninth can be any one of the nine digits not the same as the eighth.The total number of possibilities is: (10 x 9 x 9 x 9 x 9 x 9 x 9 x 9 x 9) = 430,467,210 .If matching adjacent digits were allowed there would be 1,000,000,000 possibilities.So the restriction has eliminated 56.95% of them.
Well, honey, you take the number 0.175 and there you have it - one hundred and seventy-five thousandths in digits. Easy peasy lemon squeezy!
