you would add 8-making the number 550.550 divided by 10 is 55
87 is already divisible by 3, so you could add a 0, 3, 6 or 9 anywhere in there and get the same result.
9 or 19 or 29 or 39 or 49 or 59 and so on and so forth. You could also add negative one, negative eleven, etc.
The lowest number you could add to make it divisible by 10, 2, and 5 would be 7. 23 + 7 = 30 30/10 = 3 30/2 = 15 30/5 = 6 Also, technically, you could add (-3) to make 20. 23 + (-3) = 20 20/10 = 2 20/2 = 10 20/5 = 4 Basically, you could add any number to 23 that would get a multiple of 10, since 2 and 5 are both factors of 10 to begin with.
The next nearest number divisible evenly by 10 would be 250 so you need to add 7 ro 243
542 - 387 add 3 to each number => 545 - 390add 10 to each number => 555 - 400 = 155.
If you can add the integers and they add up to a number divisible by 3, then the number is divisible by 3.
To find out if 640 is divisible by 3, we will add up the numbers that make 640 as follows: 6 + 4 + 0 = 10 We know that if the sum of the numbers that make up 640 is divisible by 3, then 640 is divisible by 3. Since 10 is NOT divisible by 3, 640 is also NOT divisible by 3. Thus, the answer to the question "Is 640 divisible by 3?" is NO. If you divide 640 by 3, you get 213.3333333.
Any number divisible by 3 has digits that add up to a multiple of 3. Adding a 1 to any of these digits or inserting a 1 anywhere in the number would make it divisible by 3.
243+7 = 250/10 = 25
Yes. If the integers making up the number add to a number divisible by 3, then it is divisible by 3.The integers 34215 add up to 15, so it is divisible by 3.34215/3 = 11405
No, it is not divisible by 3. Add all the digits of 21733, we will get 16 & 16 is not divisible by 3.
ADD 4+3. IF IT DIVIDES EASILY BY 3, YOU'RE GOLDEN. 7 IS NOT DIVISIBLE BY 3 W/OUT A FRACTION, SO SORRY, NO JOY.
Yes. Add zeros to the end of the sum that you get an keep dividing. Just make sure to ADD A DECIMAL before the zeros.;D
the rule for divisibility by 9 is that the sum of all digits of the number should should be divisible by 9. So, 3+9+0+6+5= 23. To make is divisible by 9, we think of 27 (as the next number divisible by 9) and that means if we add 4 to any digit of the number, it will be divisible. 39069/9=4341
Add the digits. If the total is divisible by three, the original number is divisible by three. It's not and it's not.
No, it is not evenly divisible by 3. The answer you get is 6,665.3333. A trick to tell is a number is divisible by 3 is to add up the digits and see if they are divisible by 3. In this case, 34 is not divisible by 3.
If its digital sum add up to 9 then it is divisible by 9
It depends on whether you mean the highest digit that you add or subtract or multiply by!
1728 is divisible by 6. 1728/6=298A number is divisible by 6 if:The number is evenThe sum of the digits is divisible by three1728 is an even number.1+7+2+8=1818 is divisible by three.Therefore 1728 is divisible by 6.Note: You can also add 1+8=9 to make it simpler to check if it is divisible by 3.
it is 2,3,6because 4152 the 2 is divisible by 2and if you add up all the numbers it = 12 and 12 is divisible by 2&3 and if a number is divisible by 2 and 3 then its divisible by 6
If a number is divisible by three you will know if all the digits of a number add up to a number divisible by three. Example: 1542 is your number, to find out if it is divisible by three you must add up the digits. 1+5+4+2=12. The number 12 is divisible by three(4x3) so therefore 1542 is divisible by three.
A number is divisible by 9 if all the digits add up to 9 or are a factor of. IF the digits add up to 9 (or a factor of 9), they will automatically be a factor of 3.Yes. Test a couple numbers divisible by 9--27, 81--and they are all divisible by 3.
