What is a three digit number that is divisible by 5 6 and 9?

All you need to do is multiply the three numbers together:5 * 6 = 3030 * 9 = 270


What is 9682 rounded with three significant numbers?

Since we want to round a value with 3 sig fig, we need to round that value to the nearest tens. To figure that out, you need to count the number of digit places from the leading nonzero digit to the ending digit based on the number of three significant numbers.96829 is the starting digit. Then, count 2 digits next to "land on" the tens digit, which is 8.The adjacent digit is 2. Since 2 is not 5 or greater, we round down the value to obtain 9680.


Do always need to regroup when you are multiplying digit or digit numbers?

No. It depends on how good you are at arithmetic.


How many 2-digit or 3-digit numbers can be formed using the digits 134568 and 9 which are diisible by 4?

48. Assuming no digit can be used more than once, the two digit numbers divisible by 4 are: 16, 36, 48, 56, 64, 68, 84, 96 8 of them. For any number to be divisible by 4, only the last two digits need be divisible by 4; so for three digit numbers, each of the two digit numbers above can be preceded by any of the remaining 5 digits and still be divisible by 4. → 5 x 8 = 40 three digit numbers are divisible by 4 → 40 + 8 = 48 two or three digit numbers made up of the digits {1, 3, 4, 5, 6, 8, 9} are divisible by 4. If repeats are allowed, there are an extra 2 two digit numbers (44 and 88) and each of the two digit numbers can be preceded by any of the 7 digits, making a total of 7 x 10 + 10 = 80 two and three digits numbers divisible by 4 make up of digits from the given set.


How many four digits numbers can be formed using 0123456789?

Assuming that the first digit of the 4 digit number cannot be 0, then there are 9 possible digits for the first of the four. Also assuming that each digit does not need to be unique, then the next three digits of the four can have 10 possible for each. That results in 9x10x10x10 = 9000 possible 4 digit numbers. If, however, you can not use the same number twice in completing the 4 digit number, and the first digit cannot be 0, then the result is 9x9x8x7 = 4536 possible 4 digit numbers. If the 4 digit number can start with 0, then there are 10,000 possible 4 digit numbers. If the 4 digit number can start with 0, and you cannot use any number twice, then the result is 10x9x8x7 = 5040 possilbe 4 digit numbers.

What steps do you take to multi digit whole numbers?

You need to find the LCM first :)


What is one and two digit numbers?

Since you need some math help, a one digit number is a number with one digit, such as 1, 2, 3, 4, etc. A two digit number is a number with two digits, such as 23, 71, 87, etc. And it seems that you need some grammar help, too. Your subject and verb do not agree; it should be "What are one and two digit numbers?". You're welcome... xD

What is the greatest possible sum of two 4-digit numbers?

In base ten it would be 19998. The sum could be much larger assuming different bases. You need to specify the base.


Which is the smallest 0.7 or 0.347?

To do this, we'll need to look at each digit in the numbers. Let's look at the first digit. They are both the same (0) so we need to look at the next digit. 7 is bigger than 3 so 0.347 is smaller than 0.7
