What is a multiple of 3 and 7 and is a even number?
42
Is 101 a multiple of 3?
101 is not a multiple of 3. The easiest way to check if a number is the same multiple of another is to divide the biggest number by the smallest, eg. 101/3 = 33.666... The closest multiples of 3 is 102 or even 99.
When is a number multiple of 6?
I think the simplest answer is any number divisible both by 2 and 3 (2x3=6), which is easy enough to figure out separately. All even numbers are divisible by 2, and all numbers divisible by 3 have their individual digits add up to a multiple of 3 (e.g. for 231, 2 + 3 + 1 = 6, and 6 is a multiple of 3, therefore 231 is also a multiple of 3). In short, multiples of 6 are even numbers whose digits add up to a multiple of 3.
Is 92 a multiple of 3?
No, 92 is not a multiple of 3. A quick way to check if a number is a multiple of 3 is: add up the digits of the number you are checking; if this sum equals 3 or a multiple of 3, then the number is a multiple of 3. So in this case, 92 --> 9+2=11, which is not a multiple of 3. If you have to you can add again, so for 11 --> 1+1=2, which is not a multiple of 3. You can always repetitively add until you get to a single digit answer: if it's 3,6 or 9 then it's a multiple of 3. Also if your sum is 9 or a multiple of 9, then the original number is a multiple of 9. To check for 6, if a number is a multiple of 3, and also a multiple of 2 (an even number), then the number is a multiple of 6.
Is 120 divisible by 2 and 3?
Yes, it is divisible by both. 120 is even, so it is a multiple of 2; 1 + 2 + 0 = 3 which is one of 3, 6, 9, so it is a multiple of 3.
