21/24 and 20/24
Why does the fraction that results from adding or subtracting fractions with unlike denominators have a different denominator?
When you add fractions that have unlike denominators, the first step is to convert them so they are expressed as fractions using the least common denominator. The result is that the answer will have a different denominator, or it may use one of the original two denominators.For example if you are adding 1/10 and 3/5, the least common denominator is 10, the problem is rewritten as 1/10 + 6/10 = 7/10But if you are adding 1/5 and 1/6, the least common denominator is 30 and the problem is rewritten as 6/30 + 5/30 = 11/30
What does find the common denominator for the fraction pairs mean?
It means find the LCM of the denominators. In order to add and subtract fractions with unlike denominators, it is necessary to convert them to equivalent fractions with a common denominator. Example: 1/4 + 1/6 The LCM of 4 and 6 is 12. 1/4 = 3/12 1/6 = 2/12
Using the fraction 4- 6 which number is the denominator?
The denominator in a fraction is always the number on the bottom. I always remembered it by thinking of the D in denominator and the D in the word down.
Equivalent fractions using least common denominator?
In order to add and subtract fractions with unlike denominators, it is necessary to convert them to equivalent fractions with a common denominator. Example: 1/4 + 1/6 The LCM of 4 and 6 is 12. 1/4 = 3/12 1/6 = 2/12
What correctly renames 78 and 56 using a common denominator?
21/24 and 20/24
Which renames 5 over 12 and 3 over 8 using a common denominator?
Divide 5 and 8 then divide 12 and 5
What pair of fractions renames five twelves and three eights using common factors?
10/24 and 9/24
Which correctly renames 7/8 and 5/6 using a common denominator?
common denominator is going to be 24 8=222 6=2*3 24=222*3 8 should be multiplied by 3 6 should be multiplied by 4 5/6=(5*4)/(6*4)=20/24 7/8=21/24 5/6=20/24```

How do you add and subtract fractions with no common denominator?
You convert them to equivalent fractions with the a common denominator. This new denominator must be a common multiple of the denominators. The Least Common Multiple (LCM) may be a recommendation but is not necessary. However, using the LCM will keep all the numbers as small as possible and that may be an advantage.
What is the highest common denominator of 18?
There is no highest common multiple. Once you get a common multiple - for example, multiplying 18 x 57, or using prime factorization to get the smallest common multiple - you can multiply it by 2, by 3, by 4, etc. and get ever-larger common multiples.
What are the strengths of using percentages?
Since percentages are based on a common denominator of 100, they are easier to add and subtract.
What is the difference between a least common multiple and a least common denominator?
The Least (or Lowest) Common Multiple (LCM) is the smallest number that is a multiple of both numbers. For example: the LCM of 10 and 4 is 20, because both 10 and 4 go into 20 and 20 is the smallest number both 10 and 4 can go into. To be able to add or subtract fractions they must have the same denominator. If the denominators are different then the fractions must first be converted into equivalent fractions with a common denominator; any common denominator can be used, but by using the Least Common Multiple of the denominators as the new denominator it keeps the numbers smaller; this smallest denominator is known as the Least Common Denominator Thus the Least Common Denominator is the Least Common Multiple of the denominators of two (or more) fractions (used when adding or subtracting fractions with different denominators). As the Least Common Multiple is used most often with adding or subtracting fractions, it is often referred to as the Least Common Denominator (because the numbers being considered are usually denominators of fractions).
How do you Add and Subtratc fractions mixed with the same denominators and Different denominators?
Different denominators: First, you find a common denominator (it can be the least common denominator, or any common denominator), and convert all fractions involved to equivalent fractions, using the common denominator. For example, 1/4 + 2/3. 12 is a common denominator; you can write this as 3/12 + 8/12.Same denominator: Just add (or subtract) the numerators, and keep the denominator. The above addition would become 11/12. Finally, you may want to check whether you can simplify the answer. Depending on how you (or the teacher) prefers the answer, you may also want to convert to a mixed fraction. In the above example, no such simplification is possible.
What is the common denominator of 52and 28?
You could use any of: 364, 728, 1092, 1456, 1820, 2184, 2548, 2912, 3276, 3640, 4004, 4368, ... though I would recommend using the least common denominator of 364.
What is nine and one thrid times eight and one eighth?
