to show cardinal value and place value
Any two digit number in which: (a) the units digit is not 0, and (b) the two digits are different will form a new 2-digit number when the digits are interchanged.
The number 11 is prime and has two identical digits.
Our numbers have a positional notation system; to know how much a given digit is, you have to know where it is in the number, with respect to the decimal point. So every number first tells you an amount, but it also holds a place in that number, so that it helps to position the other digits.
No, reversing the order of the digits of a two-digit prime number does not always result in a prime number.
Yes If a numbers last two digits (assuming that it has at least two) is a multiple of 4, the whole number is also a multiple of 4. If the last two digits are 00 (assuming in this case it has at least three digits), the number is also a multiple of 4. For example, 100 and 200 are multiples of 4.

Any number with two digits, so any number from 10 upto 99.
You can just round it off. For example, if your number is 8.38572998472654400131... that is equal to approximately 8.4 (if two significant digits is enough for your purposes) or 8.39 (if you prefer 3 significant digits).

3400 We round the number up to the nearest hundred if the last two digits in the number are 50 or above. We round the number down to the nearest hundred if the last two digits in the number are 49 or below. If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
A number is divisible by 4 if the last two digits are divisible by 4.A number is divisible by 4 if the last two digits are divisible by 4.A number is divisible by 4 if the last two digits are divisible by 4.A number is divisible by 4 if the last two digits are divisible by 4.
