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! :)
To find the total number of decimal places in a product of two numbers, you add the number of decimal places in each number. If the first number has decimal places to the thousandths (3 decimal places) and the second number has decimal places to the tenths (1 decimal place), the product will have a total of 3 + 1 = 4 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.
To find the total number of decimal places in a product of two numbers, you add the number of decimal places in each number. If the first number has decimal places to the thousandths (3 decimal places) and the second number has decimal places to the tenths (1 decimal place), the product will have a total of 3 + 1 = 4 decimal places.
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 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.
2.500
A number cannot have 3 "decimal" points in it.
