DevinTo rename the fractions 7/8 and 5/6 using a common denominator, you need to find the least common multiple (LCM) of the denominators, which is 24 in this case. To convert 7/8 to an equivalent fraction with a denominator of 24, you multiply both the numerator and denominator by 3 to get 21/24. To convert 5/6 to an equivalent fraction with a denominator of 24, you multiply both the numerator and denominator by 4 to get 20/24.
To rename 7/8 and 5/6 using a common denominator, you need to find the least common multiple of 8 and 6, which is 24. Then, convert 7/8 to an equivalent fraction with a denominator of 24 by multiplying the numerator and denominator by 3. This gives you 21/24. Similarly, convert 5/6 to an equivalent fraction with a denominator of 24 by multiplying the numerator and denominator by 4, which gives you 20/24. So, 7/8 is renamed as 21/24 and 5/6 is renamed as 20/24 using a common denominator.

What correctly renames 78 and 56 using a common denominator?
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
