It's finite (although very big). If a decimal between 0 and 1 is exactly 100 digits long, then there are 10 ways to choose the first digit, 10 ways to choose the second, and so on. This gives us 10100 ways to choose all 100 digits, which is very large (it's a googol, in fact) but not infinite.
Finite.
Terminating
its 2 types of numbers Finite numbers: have an end. they can be extremely long, but as long as they have an end at some point they are finite Infinite numbers never end. 1/3 is infinite, because the 0,3333 continues forever without even reaching exactly 1/3. 1/4 is finite, because it is exactly 0,25. So basically infinite numbers can never be written down exactly (in a decimal way), no matter how much paper you use, whereas finite numbers can.
Since it has a finite number of decimals, it is rational.
No. It can be infinite, finite or null. The set of odd integers is infinite, the set of even integers is infinite. Their intersection is void, or the null set.
They are decimal representations of numbers which stop after a finite number of digits (or continue with an infinite string of 0s).
3.14 has a finite number of digits. All numbers with a finite number of digits are rational. Pi has an infinite number of digits, AND the digits don't repeat in a regular pattern. (Numbers with repeating decimals are rational as well.)
Pressumably that refers to the fact that the number of decimals is finite (not infinite). For example, if you divide 1 / 8, you get a finite number of decimals: 0.125 It ends there. Any further decimal digits would be zero, and can be omitted. On the other hand, if you divide 1 / 3, you get: 0.33333... The 3s continue indefinitely.
Pi is an irrational number. As such, it has an infinite number of digits.
ANY number with a finite number of decimals (and some that have an infinite number of decimals) are rational.
A terminating decimal reaches an end after a finite number of digits whereas a repeating decimal, after a finite number of digits, has a string of decimals (also of finite length) that repeats forever. Thus 1.2356 is a terminating decimal. 1.456333... is a repeating decimal with the digit 3 repeating an infinite number of times. So also is 23.56142857142857...... where the string 142857 repeats to infinity. In fact, terminating decimals may be viewed as repeating decimals with zero repeating infinitely.
Repeating decimals consist of a fixed string of digits which repeat infinitely in the decimal representation of a number. These may start anywhere after a finite number of digits.
ANY number with a finite number of decimal digits is RATIONAL.(Also, numbers with an infinite number of decimals may be rational - in which case the digits repeat - or irrational.)
Some finite numbers in a set: the number of digits on your hand, the number of seats on a bus, and the number of people on earth. Some infinite numbers in a set: the number of positive integers and the number of digits in pi.
Any whole number, any number with a finite number of decimals, and some numbers with an infinite number of decimals, are rational.
infinite number of digits after the decimal point -- pi does not have a finite value.
In theory, infinite, non-recurring decimals can represent irrational number whereas fractions cannot do that. However, any non-recurring decimal number can be expressed for only a finite number of digits and so this theoretical difference cannot be attained in reality.
