the only multiples of 5 are 30.35.40.45.50, and 55
the only sum to 9 is 45
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.)
Yes, a number is a factor of 9 if the sum of its digits equals 9 or is a multiple of 9. This is based on the divisibility rule for 9, which states that a number is divisible by 9 if the sum of its digits is divisible by 9. Therefore, if the sum of the digits is 9, the number itself is divisible by 9.
If the sum of the digits is a multiple of three, the whole number is a multiple of three.
No factor of 9 has three digits. 450 is a three-digit multiple of 150 (and of 9) with a digit sum of 9.
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.
If the sum of the digits of a given number equals nine or a multiple of nine, nine is a factor of that number.
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.)
The sum of the digits is also a multiple of 9. And, if the sum of the digits is too large, you can sum those digits and keep going.
Yes, a number is a factor of 9 if the sum of its digits equals 9 or is a multiple of 9. This is based on the divisibility rule for 9, which states that a number is divisible by 9 if the sum of its digits is divisible by 9. Therefore, if the sum of the digits is 9, the number itself is divisible by 9.
If the sum of the digits of a number is a multiple of 9, the number is a multiple of 9.
