What are the common denominators of 7 and 10?
70
What is 3 over 4 plus 1 over 8?
3 1 7 4 + 8 is 8. Remember to change the denominators into common denominators. (3/4 would turn into 6/8)
How do you add or subtract rational numbers with common denominators?
you subtract the top 2 numbers and then leave the denominators the same like: 7/8-4/8=3/8. Get it?
What common denominators of 3 and 5 and 7 and 9?
Only 1.
What is the unlike denominators for 3-4 plus 7-10?
The denominator of 3/4 is 4 The denominator of 7/10 is 10 4 and 10 are not the same number so the two fractions are said to have unlike denominators.

What is the least common denominator of 21 and 7?
The Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions. I assume the 7 and 21 are the denominators of two fractions you need to add or subtract.LCD(7, 21) = 21.
How do you do least common denominators?
Find the LCM of the denominators. Since the LCM of 3 and 4 is 12, the least common denominator of 1/3 and 1/4 is 12.
What is the common denominator for 6 and 7?
There are infinitely many common denominators. The smallest of these is 42.
How do you writeWhat is a proper fraction with a denominator that is common to 7 8ths?
7/8 and 1/8 have common denominators
What common denominators of 3 and 5 and 7 and 9?
Only 1.
How so you add fractions?
If the fractions have the same denominators, just add the numerators: 2/7 + 3/7 = 5/7 If the fractions have different denominators, it is necessary to make them the same by finding the least common denominator, and converting the fractions. Example 1/3 + 1/4 The LCD for 3 and 4 is 12. 1/3 = 4/12 1/4 = 3/12 Now that the denominators are the same, we can add the numerators. 4/12 + 3/12 = 7/12 1/3 + 1/4 = 7/12
What are 1 over 2 and 1 over 4 common denominators?
4
