102 is the smallest three digit number with different digits.
Here it is ! 10,234 !!
Among whole numbers, 1,023,456 is.
All five digit numbers have three digits. The smallest five digit whole number is 10,000
Since there are no specifications --- Positive integer: 102 Positive rational number: 0.12 Negative integer: -987 Negative exponent: -87^9
111111. Since there are six digits, there must be a repeated digit, so why not repeat all ones to get the smallest one.
1,023,456 unless you consider -9,876,543.
13,579 or .13579 . If I'm allowed to repeat digits, then you are 11,111 or .11111 .
00000 or 11111
In a proper fraction the numerator is smaller than the denominator. Since every two-digit number is larger than every one-digit number, there must be a one-digit numerator and two-digit denominator comprising 3 digits total. The greatest fraction will be the one with the largest possible numerator and smallest possible denominator. Choose a numerator of 9 (the largest one-digit number) and a denominator of 10 (the smallest 2-digit number). All 3 digits are different. The answer is 9/10.
9876 is the largest four digit number you can make if all the digits must be different.
The smallest prime number in which all of the digits are also prime is 2.The smallest multi-digit prime number in which all of the digits are also prime is 23.
111111 Any 6 digit number less than that would require a 0, which is an even number.
The smallest number would be 10,000,000 because the one is the lowest number that could possibly go in the ten millions place. After that, you can put all zeros.
