What is the least common denominator of 2 6 7 and 12?
To find the common denominator of two fractions, you find the least common multiple of the denominators. The multiply the numerators by whatever you multiplied the denominator by to get an equivalent fraction. example: 1 + 2 = 10 3 4 12 the least common multiple of 3 and 4 is 12 so, 4 + 6 = 10 12 12 12 which can be reduced to the answer of 5 6
To find the least common denominator, list the multiples of each denominator. The lowest one they have in common is the LCD. For example: 2/3 and 3/4: The multiples of 3 are: 3, 6, 9, 12, 15, 18, 24... The multiples of 4 are: 4, 8, 12, 16, 20, 24... The common multiples are 12 and 24. Since 12 is the least, it is the LCM.
You find the least common multiple of the denominators [or least common denominator]. Basically, the Least Common Denominator equals the two denominators multiplied together and then divided by any common prime factors. It is easy to see that the numbers 2 and 3 have a common denominator of 6. But the number 4 and 6 do not have a least common denominator of 24, because both numbers are factors of the number 12 (the least…
What therteen digit number divided with a single digit from 1 to 12 will result in a remainder of 1?
You won't get a remainder of 1 if you divide by 1. If you want the same for all the numbers from 2-12, you must get a common denominator of all the numbers from 2-12. Any common denominator might do, so you could just multiply all those numbers together; or (to get all solutions) get the least common denominator. Next, find a multiple of this common denominator that has 13 digits, and add one to…
You make a list of the multiples of both denominators and find the smallest one they both have. Then multiply the numerator by the same number to get the least common denominator. Example: 1/2 and 1/3. 0,2,4,6,8,10,12,14,16 and 0,3,6,9,12,15,18,21. 2x6=12, use the six. 1x6=6. 3x4=12, use the 4. 1x4=4. 1/2 and 1/3 =6/12 and 4/12. Takes practice.
