What is the total of digits used in numbers from 51 to 5001?
To find the total number of digits used in numbers from 51 to 5001, we can break it down into two parts. Numbers from 51 to 99: Each number in this range has 2 digits, so there are 49 numbers in total, resulting in 49 x 2 = 98 digits. Numbers from 100 to 5001: Each number in this range has 3, 4, or 5 digits. a. For numbers from 100 to 999, each number has 3 digits, so there are 900 numbers in total, resulting in 900 x 3 = 2700 digits. b. For numbers from 1000 to 5001, each number has 4 or 5 digits. There are 4002 numbers in total, and if we assume each has 4 digits, it would be 4002 x 4 = 16008 digits. Adding all these together, the total number of digits used in numbers from 51 to 5001 is 98 + 2700 + 16008 = 18706 digits.
How can you divide any number by 9?
Add the digits of the number. If that total is divisible by nine, so is the original number. Example: 12,345,678 The digits total 36. 36 is divisible by 9. So is 12,345,678.
The total number of five digit numbers that can be be formed digits 12345 is?
It is 120 if the digits cannot be repeated.
What are the divisiblty rules for 9 and 4?
If the last two digits of a number are divisible by 4, the whole number is divisible by 4. If the sum total of the digits in a number are a multiple of 9, the whole number is a multiple of 9.
The sum of its digits is 11?
It you add up all the digit in the number they will total 11. For example the number 425 has digits that sum to 11. (4 + 2 + 5 = 11)
