Why is the size of a decimal number not necessarily determined by the number of decimal places notated?
Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude. Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size).

What is a decimal which has a final number of digits?
It is a terminating decimal.
Why do you separate 5 digits in tele phone number?
Most people can remember strings of 4-5 digits. Longer strings are harder.
Repeating decimal definition?
A repeating decimal is a number expressed in decimal form in which, after a finite number of miscellaneous digits, the number continues with a string of a finite number of digits which repeats itself without end.
When multiplying two factors each one with a decimal place how many decimal places should the answer have?
You need to add up the number of digits to the right of the decimal to find the number of digits in the answer. If the first factor has 2 digits to the right of the decimal point and the second factor has 3, the final answer will have 5 digits to the right of the decimal point.

Is a decimal number with two digits is sometimes equal to a decimal number with three digits?
Only if the final digit, after the decimal point, is zero.
How many strings of four decimal digit have exactly three digit that are nine?
The number of strings of four decimal digits that have exactly three digits which are nine is the number of ways to choose three places to choose the nines multiplied by the number of possibilities for the other digits (because you can put all of the possibilities in an array so that each column has a different way of arranging the nines and that each row has a different set of other digits (because they do not affect each other)). The number of ways to choose the three places to choose the nines is the same as the number of ways of choosing 4-3=1 spot for there not to be a nine. The number of ways of choosing 1 spot where there are 4 spots is 4 (the first, the second, the third, or the fourth). Since there are 9 digits that are not nine, the number of choices for the other digits is 9 (since there is only one digit). Thus, there are 4*9=36 strings of four decimal digits that have exactly three digits which are nine.

What is a decimal number which ends after a finite number of digits after the decimal point is called?
It is a terminating decimal.

A repeating decimal is a number expressed in decimal form in which, after a finite number of miscellaneous digits, the number continues with a string of a finite number of digits which repeats itself without end.
What is a number with one or more digits that is to the right of a decimal?
It is a decimal fraction.
Is 7.11 rational or irrational?
A number with a finite number of decimal digits is always rational. (If the number of decimal digits is infinite, the number is rational only if there is a repeating pattern.)
A decimal with finite number of digits?
Repeating
What is a rational number in decimal form that has a finite number of digits after the decimal point?
I think it's a repeating decimal.
