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```

CoachTo rename 7/8 and 5/6 using a common denominator, we need to find the least common multiple (LCM) of 8 and 6, which is 24. To convert 7/8 to an equivalent fraction with a denominator of 24, we multiply the numerator and denominator by 3 to get 21/24. For 5/6, we multiply the numerator and denominator by 4 to get 20/24. Therefore, 7/8 is equivalent to 21/24 and 5/6 is equivalent to 20/24.
Ah, isn't that lovely? To rename 7/8 and 5/6 using a common denominator, we need to find a number that both 8 and 6 can divide into evenly. The smallest number that works is 24. So, 7/8 becomes 21/24, and 5/6 becomes 20/24. Just like that, we've given them new names while keeping their values the same. Happy little fractions!
Alright, honey, to rename 7/8 and 5/6 with a common denominator, you gotta find the least common multiple of 8 and 6, which is 24. So, for 7/8, you multiply the numerator and denominator by 3 to get 21/24. And for 5/6, you multiply the numerator and denominator by 4 to get 20/24. Voila, now they both have a common denominator of 24.

Which renames 5 over 12 and 3 over 8 using a common denominator?
Divide 5 and 8 then divide 12 and 5
Why do you need a common denominator when you add fractions?
Unless you are using a calculator that adds them for you, it is much harder to add fractions with uncommon denominators. Having the same denominator allows you to only have to add the numerators for your answer.
How do you write equivalent fractions with the lowest common denominator?
Well, isn't that just a happy little question! To write equivalent fractions with the lowest common denominator, you first find the least common multiple of the denominators. Then, you rewrite each fraction using that common denominator. It's like painting a beautiful landscape - just take your time, follow the steps, and soon you'll have a lovely set of equivalent fractions.
What is the step to finding the least common denominator?
There are many ways to find the lowest common denominator (LCD). One way is to list out all the factors of both numbers and find the common one. Whichever one is the lowest is the LCD. But if you're using larger numbers you can do trial and error or multiple the denominators.
How can factors help you find a common denominator?
They can help you find a common denominator by the bottoms one of each fraction if the top ones don't have the same denominator. Then find the simplest or non-simplest denominator. Like when you have 2/7+ 2/3=? Well that equals: 20/21. How you find that out is by finding what 7 and 3 have in common is by using a multiplication table until you reach a number they both equal because 7X3= 21 so that's how you get the bottom number. Then you just add the top and that's how you do fractions and the denominator.
