You would need infinitely many digits to write all numbers. However, to write all whole number (integers) you would need 4243.
It is 180,001.
I am not quite sure what you mean, but numbers that are very large can be written in scientific notation, so that you don't have to write out all the digits. Assuming, of course, that you only need a limited amount of significant digits.

Any number that you can completely write down using digits is rational.Let's try to write 2.51 completely with digits:2.51That's it! We're pretty sure that 2.51 is rational. The official math definition of a rational number is: A number that can be writtenas a fraction made of whole numbers. Let's try and write 2.51 as a fractionmade of whole numbers:251/100We did it again! 2.51 is definitely rational.
The number of digits is log10(Graham's number) rounded up to the next whole number; this number is still extremely large and impossible to write in simplified form.
Write 2 ways in which whole numbers and decimal numbers are different
There are two numbers between 740 and 760 whose digits sum to 17: 746 and 755
-- The decimal system (base-10) uses 10 digits to write all numbers. -- The binary system (base-2) uses 2 digits to write all numbers.

Smallest Fraction: 3/(4*5)Largest Fraction: (4*5)/3Smallest Mixed Fraction: 3 4/5Largest Mixed Fraction: 5 4/3 = 6 1/3Smallest Fraction (Digits): 3/54Largest Fraction (Digits): 5/34Small numbers divided by large numbers yield small numbers; large numbers divided by small numbers yield large numbers.
-- It's rational if there's any way to write it as a fraction that has whole numbers on the top and bottom. -- It's rational if you can write it down on paper completely, using digits.
