0.
Let's assume, or hope, that the blank is after those numbers. 67_ and 45_ For a number to be divisible by three, the total of the number's digits has to be divisible by three. 672 and 450
To determine what digit can be placed in the blank to make a number divisible by 3, you need to ensure that the sum of all the digits in the number, including the blank, is divisible by 3. For example, if the number is 25_, you would calculate the sum of 2 + 5 + _ and check which digit (0-9) makes the total divisible by 3. Once you find the appropriate digit, you can fill in the blank.
smallest 4-digit number divisible by 2 = 1000
2. To test a number to be divisible by 3, add up the digits and if the sum is divisible by 3, so is the original number. If not, the excess over a multiple of 3 gives the remainder when the original number is divided by 3. Subtract this remainder from 3 and this gives the smallest digit to replace the blank; unless the remainder is 0, in which case the blank can be replaced by a 0: 8 + 6 + 9 + 3 + 5 = 31 → 31 ÷ 3 = 10 remainder 1 Replace blank by 3 - 1 = 2: 826935 is divisible by 3
