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 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 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 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.
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
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).
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.
