6. To check for divisibility by 9, add the digits of the number together and if the sum is divisible by 9, then the original number is divisible by 9. If the test is repeated on the sum(s) until a single digit remains, then this is the remainder when the original number is divided by 9. Subtracting this remainder from 9 will give the smallest number that needs to be added to to the original number to make it divisible by 9. For 75: 7 + 5 = 12 1 + 2 = 3 so 75 ÷ 9 has a remainder of 3, therefore add 9 - 3 = 6 to 75 to make it divisible by 9. (75 + 6 = 81 = 9 x 9).

Yes it is. If the digits of a number added together will divide exactly by three (or nine) then the number itself will also divide exactly by 3 or 9. In this case, 1+8+9=18... which is exactly divisible by 3.

Answer: 2A number is divisible by 3 if the sum of its digits is a multiple of 3.Now 2+1+4=7. If we add 2 more it is 9 which is a multiple of 3.So 216 is divisible by 3 since 2+1+6=9 which is a multiple of 3.

Nope - 1038 is an even number and thus is divisible by 2. Its digits added together total 12 - which is divisible by 3... therefore the original number is also divisible by 3 !!
