There are twelve possible solutions using the rule you stated.
144 is divisible by 12 and 9.
There are the same number: any twelve digit palindrome is just an eleven digit palindrome with its central digit repeated. In general, if we are considering numbers of n digits: For even values of n, the number of palindromes is 9 x 10n/2 - 1 For odd values of n, the number of palindromes is 9 x 10(n-1)/2
Divide the two-digit number by the one-digit number. If the remainder is zero then the 2-digit number is a multiple and if not, it is not.
10,000,000 is the smallest 8 digit number 99,999,999 is the largest 8 digit number
It is called a twelve-digit number. Its exact name will depend on the number.

60, 72, 84, 90 and 96 each have twelve factors.
None. A fraction is a simple division. 2/4 is 2 divided by four. No one digit number can divide into twelve equally. Therefore, you cannot write a one-digit number to equal twelve.
