If someone had 1 x 1019 (which would be a 20 digit number) pounds then they would have 10 quintillion pounds! I suppose this would make them a quintillionaire!
Of course this terminology assumes you are using the American / seemingly "modern British" definitions and not the traditional English definition.

Are repeating decimals an irrational number?
A repeating decimal is a rational number. Its value is(the repeating set of digits)/(as many 9s as there are digits above).
Thirty-six and twenty-two hundredths?
36.22 As a decimal number, shown above.
What can be used to signify the repeating digits in a repeating decimal?
The re are two ways: Ellipses = "..." A dot above the repeating string.
Does adding a decimal to a two digit number make the number three digits?
Generally no. Three digits usually refers to whole numbers. In the example above I would phrase the question to the effect "Please provide answers to a resolution of one decimal place".
How do you divide with decimals in the dividend?
Put the decimal point for the quotient exactly above the decimal point in the dividend. Then forget about it, and just keep your digits lined up as you do the division. The decimal point winds up exactly where it belongs in the quotient.
Why is it important to line up the decimal?
It is important for you to line up the decimals vertically the way I did above so that you can keep track of the place-value position of the digits.
How many significant digits does this number have 2.5000 times 104?
2.5000 has five significant digits and 104 has three significant digits. Therefore, the product should have three significant digits, and the answer is "260.". Note that the zero has to be made significant, so a decimal point is needed after the zero or you could put a vinculum (horizontal line) above the zero.
What is the greatest 3 digit decimal less than 1?
It depends on what you mean by three digit decimal. If you mean three digits after the decimal, then it's 0.999. However, if you mean three digits in the number, then it's 0.99.
What does a point over a number mean in mathematics?
that dot means reccurent, its usually above a decimal number, & means that digit continues on forever. E.g. put 1/3 as a decimal. this wouldn't be 0.3 it would be 0.3 (with the dot above the 3) so for the example above the answer is 0.333333333333333333333333333(continues on forever) By the way, the number can have a dot on more than one of its digits
What does find the sum of the digits of each number above mean?
Add the digits together. The sum of the digits of 23 is 5.
What does 4 over 7 equal in a decimal?
4/7 = 0.571428571428.... the sequence of digits, 571428 repeats indefinitely and this is known as recurring decimal. To indicate this a line is drawn above the recurring digits. ............______ 4/7 = 0.571428 NOTE : To enable the line to be correctly positioned a number of dots are shown but in text books and whilst undertaking written mathematics work these dots would not be present.
How do you place the decimal point in the quotient when dividing a decimal by a whole number?
The decimal point goes in the quotient the moment you reach the decimal point in the dividend and need to use the digit in the tenths column. When using the "Bus stop" method, the digits will line up so that the decimal point goes in the quotient directly above the decimal point in the dividend.Using the Bus stop method, it is easiest to put the decimal point in the quotient above the decimal point in the dividend first (before any any division calculation is done) and then do the division by ignoring the decimal points and putting digits in the quotient as normal; except if once all the digits of the dividend have been used there is a non-zero remainder, zeros can be added to the end of the dividend as they are trailing zeros after a decimal point which make no difference to the number.eg dividing 1.2 by 5:First place the decimal point in the quotient over the decimal point in the dividend:_____.___------5_|_1.2Now divide as normal:____0.2__------5_|_1.2____1 0____----______2Used up all the digits of the dividend but have a remainder, so add trailing zeros after the decimal point and finish the division:____0.24__--------5_|_1.2000____1 0____----______20______20______---_______0Only needed one extra 0, but it did not hurt putting three of them.→ 1.2 ÷ 5 = 0.24Sometimes the decimal may recur or not terminate; in that case, stop when the required level of accuracy is reached (rounding by calculating a further digit and using that as the deciding digit).
