Answer:

1: A) No

2: A) No

3: B) Yes, because the sum of the digits 9+4+0+3+2=18, which is divisible by nine

4: C) Yes, because the last digit in the number is 6, which is an even number

Step-by-step explanation:

Lets start with the first one. The divisibility rule for five is that if the number ends in a zero or a five, then it is divisible by five. Does 1,112 end in a five? No, so our answer is A.

For the next one, recall that the divisibility rule for ten is that the number has to end in a zero. Does 10,000,058 end in a zero? No, the last digit is eight, so the answer is A.

For the third one, recall that the divisibility rule for nine is that the sum of all the digits of the number must equal a number that is divisible by nine in order for you number to be divisible by nine.

9+4+0+3+2=18

Is 18 divisible by nine? Yes, so the answer to the third one is B.

For the last one, we need to remember that in order for a number to be divisible by 2, it must end in either a 0, 2, 4, 6, or 8. Does 201,086 end in one of those digits? Yes, it ends in a six, so our answer is C.

Answer:

7) No.

8) No.

9) Yes, because the sum of the digits is 9 + 4 + 0 + 3 + 2 = 18, which is divisible by 9.

10) Yes, because the last digit in the number is 6, which is an even number.

Step-by-step explanation:

7) 2 is not divisible by 5 in any form. If you look further, the number is 12. And     12 cannot be divided by 5.

8) There is no way you can divide 58 by 10. 8 cannot be divide by 10.

9) The third option suggested that the first digit was the reason the number was divisible. 90,000 in value. But when finding if a number is divisible by another number, never look at the first digit, but look at the last.

In this case, 9 is a hard number, so we will have to apply the next method when finding out if a number is divisible by another. Thats when we add all of the values together. We got a result of 18, which is divisible by 9.

10) Anything that is even, can be divisible by 2. In this case, the last digit (6) was even.
