a) This could be a special numbering system, such as the Dewey Decimal System used in libraries. Such as 620.105.3.1.
b) Or do you refer to repeating decimals, such as 6.304 304 304.
3 periods
3 ones as decimal: 3 ones = 3 and it is a whole number = 3.0 in decimal
The decimal number midway between 3 and 4 is 3.5
A period is a group of 3 digits in a number. For example: 6,756,215,985,000,000 .this number has 5 periods, because every group of 3 digits counts as a period. Another example: 214,587,425. this number has 3 periods. another example: 12. this number has 0 periods. another example: 54,554,215,487,256,542,154,252,563,253,256,896,585,487,545,468. (this number has 15 periods.) well...I hope I helped! :)
When multiplying a number with decimal places to the hundredth (2 decimal places) by a number with decimal places to the tenths (1 decimal place), you add the number of decimal places together. This results in a total of 2 + 1 = 3 decimal places in the product. Therefore, the product will have 3 decimal places.

The "periods" in a big number are the groups of 3 digits between the commas. The correct way to write this big number is: 645,165,758 ... in 3 periods.

17.635 already is rounded to 3 decimal places.
the decimal number for 3 & 9/10 is 3.90
The product of a number with decimal places to the hundredths (2 decimal places) and a number with decimal places to the tenths (1 decimal place) will have a total of 3 decimal places. This is determined by adding the number of decimal places in each factor (2 + 1 = 3). Thus, the resulting product will be expressed to three decimal places.
A number cannot have 3 "decimal" points in it.
2.500
At most 3.
3/4 = 0.75 a terminating decimal
