No, a number with a 9 in the ones place is not always divisible by 3. For a number to be divisible by 3, the sum of its digits must be divisible by 3, regardless of the digit in the ones place. For example, the number 29 has a 9 in the ones place, but its digit sum (2 + 9 = 11) is not divisible by 3.
What else can I help you with?
If a number has a 9 in the ones place is it always divisible by 3?
No, a number with a 9 in the ones place is not always divisible by 3. For a number to be divisible by 3, the sum of its digits must be divisible by 3, not just the last digit. For example, the number 39 (3 + 9 = 12, which is divisible by 3) is divisible by 3, but the number 29 (2 + 9 = 11, which is not divisible by 3) is not.
Is 305 divisible by 10?
No; for a number to be divisible by 10, the last number (ones place) must be zero.
How do you find if a number is divisible by 5?
To find if a number is divisible by 5, the digit in the ones place has to be 0 or 5.
Why is a number with zero in the ones place divisible by 5?
Because such a number is divisible by ten, and five is a factor of ten. Hence, such a number is also divisible by five.
Why does a number with 0 in the ones place is divisible by 10?
A number with 0 in the ones place is divisible by 10 because of the definition of divisibility. A number is divisible by 10 if it can be expressed as 10 times another integer. Since the presence of 0 in the ones place indicates that the number is a multiple of 10, it confirms that the number can be evenly divided by 10 without any remainder.

Which digits can be in the ones place of a number that is didisible by 2?
2,4,6,8,and 0 are divisible by 2 in the ones digit. Zero is only divisible in a number with 2 digits or more. 0 itself is not divisible by 2.
Are all the number with 0 ones place are divisible by 5 and 10?
Yes
Why is a number with 0 in the ones place divisible by 10?
The number immediately to the left of the ones place is the tens place or the 101 place. Since the value of any digit, d, there would be d*101 = d*10, it will be divisible by 10. The next number to the left is the hundreds place or the 102 place. Since the value of any digit, d, there would be d*102 = d*100, it will be divisible by 10. All the numbers further to the left have place values that are higher integer powers of 10 and so whatever the digit in that place, they will be divisible by 10. And so the answer follows.
How can you tell that 28655 isn't a prime number?
Any number that has a 5 or 0 in the ones place is divisible by 5. If a number is evenly divisible by another number, it is NOT prime.
Is 108098 divisible by 5?
No, a trick you can use is that the ones place in the number has to either be a 5 or a 0 in order for it to be divisible by 5.
What do you know about any number that has a five in the ones place?
its evenly divisible by 5 with no remainder
Is 185 composite or prime?
185 is composite because anything that has 5 in the ones place is always divisible by 5. A prime number is a number that can only divided equally by itself and 1, so since 185 is divisible by 185, 1, 5, and 37, it is not a prime number.
