Least common multiple of 3 and 9?
The least common multiple of 3 and 9 is 9. because: Multiples of three are: 3, 6, 9, 12, 15... Multiples of nine are: 9, 18, 27, 36.... The Least Common Multiple (LCM) there in both of the numbers is 9.
What is the least common multiple of 6 and 9?
The LCM of 6 and 9 is: 18The prime factorization of 6 is 2 * 3The prime factorization of 9 is 3 * 3The LCM of 6 and 9 is 2 * 3 * 3 = 18Another method is to compare the multiples of each number in the set.The multiples of 6 are 6, 12, 18, 24, 30, and so onThe multiples of 9 are 9, 18, 27, 36, and so onSo the lowest common multiple is 18, as it's the smallest number that is in both lists.6x1=6 6x2=12 6x3=189x1=9 9x2=18 9x2=18The Least Common Multiple (LCM) for 6 9 is 18.
What is the common multiple of 2 3 and 9?
Since 9 is a multiple of 3, to answer this question we want only the multiples of 3 that are also multiples of 9. Thus, we need not consider 3 in answering this question. Thus we want to know the common multiples of 2 and 9. For positive integers, examples are 9x2x1=18, 9x2x2=36, 9x2x3=54, 9x2x4=72, .... Keep adding 18 to get more in this infinitely large set. This is an unusual question; was it an assignment for a class? For most math problems, it is only the least common multiple (LCM) that is needed, which is 18 for this question.
What is two thirds minus three fourths?
First, find the least common multiple of 4 and 3 (the denominators). This is 12. 3/4 = 9/12 and 2/3 = 8/12 So the revised question is: 9/12 minus 8/12 easy enough? (pssst. the answer is one twelfth)
What is two ninths of 3?
2/9 time 3 = 2 x 3/9 = 6/9 = 2/32/3
What is then least common multiple of 2 and 3 and 9?
The least common multiple of the numbers 2, 3 and 9 is 18.
What are examples of multiples?
4 is a multiple of 2. 9 is a multiple of 3.
What is the LCM of 2 4 6 and 9?
The LCM of 6, 9, 4, and 2 is 36. The LCM must include at least 2·2 to be a multiple of 4 and 3·3 to be a multiple of 9. 2·2·3·3 = 36 = which is also a multiple of both 2 and 6.
What is the Least common multiple of 9 and 2 and 3?
The Least Common Multiple (LCM) for 2 3 9 is 18.
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.
What is the LCM for 2 and 3 and 9?
The Least Common Multiple (LCM) for 2 3 9 is 18.
Is 297 divisible by 3?
Yes, the quotient is 99 when you divide by three, but to check for divisibility (by 3 or 9), do this: If the sum of the digits is a multiple of 3 [9], then the number is a multiple of 3 [9]. This only works for 3 and 9. So for 297: 2+9+7 = 18, which is a multiple of 9 and 3, so it is a multiple of 3 (and a multiple of 9, as well; though the question didn't ask for that).
How do you do 2 over 3 minus 4 over 9?
2/3 - 4/9=? -you have to change the 2/3 for they can have the same denominator as 4/9, so you multiple it by 3 so it can change into a 9, and what you do to the bottom you have to do to the top, so also multiple 2 x 3 and you end up with 6/9 - 4/9= 2/9
What is a multiple of 6 and 9?
18(6 * 3)(9 * 2)
Is 270 a multiple of 3?
2+7+0=9 and 9 is divisible by 3. Therefore 270 is a multiple of 3.This works for 3,9 and 27.
What is the least common multiple of 2 3 9 and 11?
The LCM of 2, 3, 9 and 11 is 198.
Is 3 a multiple for 9?
No - 9 is a multiple of 3.
