Yes, all multiples of 9 are also multiples of 3.but they're not all of them. Every multiple of 9 is also a multiple of 3, but there are more multiples of 3 besides those.

Yes, multiples of 8 are also multiples of 2 because 8 is a multiple of 2 itself.

multiples of 8 are also multiples of 2 because anything you times by 8 is an even number

18

Yes.

Well, it depends. Since 9 is a bigger number than 3, logic says that not all multiples of three are all also multiples of 9. However, 9 is a multiple of 3 (3x3=9), therefore if we count up the 3x table, every third number will also be a multiple of 9. Eg: 3,6,9,12,15,18. 6 numbers, two are multiples of 9, 9 and 18.

yes

Yes they are.

Yes, but that doesn't cover all of them. Every multiple of 9 is also a multiple of 3, but there are more multiples of 3 besides those.

4 and 8 are multiples of 2. 6 and 9 are multiples of 3. 40 and 50 are multiples of 10.

Assuming you mean that you want the number of multiples of each, then for 1-100: number of multiples of 2 = 50 number of multiples of 3 = 33 number of multiples of 4 = 25 number of multiples of 6 = 16 number of multiples of 8 = 12 number of multiples of 9 = 11 Assuming you mean that you want the numbers that are multiples of 2, 3, 4, 6, 8 or 9, then some numbers may be multiples of more than one (for example 12 is a multiple of 2, 3, 4 and 6) and so a straight addition of the number of multiples of each cannot be done: Consider 2, 4 and 8 Every multiple of 4 or 8 is also a multiple of 2, so all the multiples of 4 and 8 are counted by the multiples of 2. Consider 3 and 9 Every multiple of 9 is also a multiple of 3, so all the multiples of 9 are counted by the multiple of 3 Consider 2, 3 and 6. Every multiple of 6 is an even multiple of 3, so are counted in both the multiples of 2 and 3. So the total number of multiples of 2, 3, 4, 6, 8 or 9 is the number of multiples of 2 plus the number of multiples of 3 minus the number of multiples of 6: For 1 to 100, Number of multiples of 2 = 50 Number of multiples of 3 = 33 Number of multiples of 6 = 16 So number of multiples of 2, 3, 4, 6, 8 or 9 in 1-100 is 50+33-16 = 67. Assuming you mean that they are multiples of all of 2, 3, 4, 6, 8 and 9, then they must be multiples of the lowest common multiple of 2, 3, 4, 6 ,8, 9 2 = 21, 3 = 31, 4 = 22, 6 = 2131, 8 = 23, 9 = 32 LCM = highest power of the primes used = 2332 = 72 Thus all numbers that are multiples of 2, 3, 4, 6, 8 and 9 are multiples of 72, which means between 1 and 100 only 1 number is a multiple of all of them, namely 72

yes. they are still multiples of 2

Since 2 is a multiple of 6, all multiples of 6 are also multiples of 2.

yes, every multiple of 9 is a multiple of 3, but that doesn't cover all of them ...there are more multiples of 3 besides those.

Since 8 is a multiple of 2 and 4, all multiples of 8 are also multiples of both of them. Thus, Jose and maria are both correct.

The numbers 3, 5, 7, 9, 11, 13, 15, 17, and 19 are not multiples of 2.

The multiples of 6 is 6,12,18,24,30,36,42,48,54,60,66,72,78,84,90.................. The multiples of 9 is 9,18,27,36,45,54,63,72,81,90,99,108,117,126,135...............

ALL even numbers are multiples of 2... so if there is an uneven multiples of six than they aren't multiple of two.

Yes. In fact all even numbers (not just 4) will share their multiples with 2.
