It depends on the degree to which you are rounding.
To the nearest 60 (eg minutes to hours) there are 60 including itself.
To the nearest 30 (eg days to approx months) there are 30 incl itself.
and so on.

What is the smallest three digit even number using the numbers 123?
it would be 0000.01
How do you divide two digit by three digit numbers?
I think that you would just add a .0 to the end of the two digit number, thus making it three digit, then divide. At the end, you have to put the decimal on the answer in the right place, though.
How would you round to the hundredth?
Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the thousandths place. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.
How many even 3-digit numbers can be formed from digits 1 2 3 5 if each digit can be used only once?
For the first digit there would be 4 options For the second digit there would be 3 options for the third digit there would be 2 options Thus 4*3*2 = 24 three digit numbers can be formed if each digit can only be used once in a 3 digit number made.
How many even 3-digit numbers can be formed from digits 0 1 2 4 5 7 9 if each digit can be used only once?
To solve this question, two cases must be considered:Case 1: The three-digit even number ends with 0.If the three-digit number ends with 0, then the number must be even. After the digit 0 is used, six digits remain. After any one of these six digits is chosen to be the first digit, five digits remain. To complete the number, any of the five remaining digits could be chosen to be the second digit of the number.___6___ * ___5___ * ___1___ = 30 three-digit even numbers ending in 0.1st digit-------2nd digit----3rddigit (0)Case 2: The three-digit even number does not end with 0.If the three-digit number does not end with 0, it can end with 2 or 4. Therefore, there are two possibilities for the third digit. The first digit could be any of the remaining digits, EXCEPT 0: if 0 were the first digit, it would not be a three-digit number. Therefore, there would be five possible digits for the first digit. 0 could be used as the second digit, along with the four remaining digits that were not previously used.___5___ * ___5___ * ___2___ = 50 three-digit even numbers not ending in 0.1st digit-------2nd digit-----3rddigit (0)The total number of three-digit even numbers is 80, since 30 three-digit even numbers ending in 0 plus 50 three-digit even numbers not ending in 0 equals 80.
How is 311.190 rounded to the front end digit?
3 is your front end digit nothing in the numbers can round up so it would seem that 300 would be it

it would be 0000.01
How many three digit numbers have digits that add up to zero?
None. The only way for it to be possible would be 3 zeros which is not considered a 3 digit numbers.

How do you round to the nearest tenths place?
Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the hundredths place. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out.

What is 7.039521 to three decimal numbers?
You would round the number up - to read 7.040
How does rounding work in the decimal system?
In the decimal system, when rounding numbers you look at the digit to the right of the desired decimal place. If that digit is 5 or greater, you round up; if it's less than 5, you round down. For example, if rounding to the nearest whole number and you have 4.6, it would round up to 5, but if you have 4.4, it would round down to 4.
How would you round to the nearest cent?
That's the same as two decimal places. Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the thousandths place. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.
When using the pythagorean theorem if you had to round to the nearest hundred how would you do so?
Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the tens place. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.
