The answer is 333. Homework,yeh
I think the answer is 612!1 (tens digit) which is odd is half of 2 (hundreds digit) and the sum is (6+1+2=9).

21 ways assuming no leading zeros, that is the smallest possible number with three digits is 100 Otherwise if leading zeros are allowed, it is 28 ways. For three digit numbers the first digit can be 1-6. Leaving the remaining two digits to be 6-value_of_first_digit. For first digit 6, the remain two digits sum to 0 which means they can only be 00, ie the number 600 - 1 number For first digit 5, the remain two digits sum to 1 which means they can be 01 or 10, ie the numbers 501, 510 - 2 numbers For first digit 4, the remain two digits sum to 2 which means they can be 02. 11, 20, ie the numbers 402, 411, 420 - 3 numbers etc It can be seen that the number of ways of making a two digit number (with leading zeros) sum to a number less than 10 is the required sum plus 1. So for the remaining first digits, the number of ways are: 3 -> 4 ways, 2 -> 5 ways, 1 -> 6 ways. Thus the total number of ways is 1 + 2 + .. + 6 = 21 If leading zeros are permitted, so that, for example, 060 (60) and 006 (6) are considered as three digits numbers, then there are a further 7 ways with a first digit of 0, making a total 28 ways.

A number is divisible by 3 if the sum of its digits is a multiple of 3. A number is divisible by 6 if the sum of its digits is a multiple of 3 and it's even. A number is divisible by 9 if the sum of its digits is a multiple of 9.
Yes, yes, and no. 3- sum of digits must be multiple of 3. 6- sum of digits must be multiple of 3 and number must be even (multiple of 2). 9- sum of digits must be multiple of 9. (The sum of the digits here is 21.)
you add up the digits, and if the sum is a multiple of 3, then the number is divisible by 3!
If the sum of the digits is a multiple of three, the whole number is a multiple of three.
Oh, dude, a factor of the sum of the digits being 3 or a multiple of 3 just means that if you add up all the digits in a number and it equals 3, or if that sum is a multiple of 3, then that number has a factor that fits the bill. So, like, if you have a number where the digits add up to 3, or 6, or 9, or any multiple of 3, you've got yourself a match! It's like finding a snack in your pantry that fits your cravings perfectly – it just works out, man.
If the number is even, it is a multiple of 2 If the sum of the digits make a number divisible by 3, the number is a multiple of 3 If the number ends in 5 or 0, the number is a multiple of 5 If the number is divisible by 2 and 3, the number is a multiple of 6 If the sum of the digits make a number divisible by 9, the number is a multiple of 9
The sum of the digits is a multiple of 3
No factor of 9 has three digits. 450 is a three-digit multiple of 150 (and of 9) with a digit sum of 9.
Any number whose sum of its digits are equal to a multiple of 3, is divisible by 3. In this instance, the sum of the digits of the number 34215 is equal to 15, which is divisible by 3, and therefore the number is divisible by 3.
If the sum of the digits is a multiple of 3, yhen the number is divisible by 3.
Test of divisibility by 3:Sum of digits = 1+2+1+5+3 = 12(a multiple of 3)If sum of digits is a multiple of 3 then the number is divisible by 3.So, 12153 is divisible by 3.
