What is the least common denominator for 3 and 7?
There is none. A least common denominator is to be found between or among fractions. 3 and 7 are not fractions.
What is a common denominator of the fractions 2-3 and 3-5?
15
What is the least common denominator of 3 5 and 5 12 they are fractions 3 over 5 and 5 over twelve?
The least common denominator of the fractions 3/5 and 5/12 is 60.
What are the two new fractions that you will add together now that you have a common denominator?
They are equivalent fractions. For example, if you are adding 1/2 and 1/3 and the common denominator is 6, the two new fractions are 3/6 and 2/6 respectively.
What is the least common denominator of 3 and 5?
The Least Common Multiple of 3 and 5 is 15, which would be the denominator to use for fractions with the denominators 3 and 5.

The least common denominator of the fractions 3/5 and 5/12 is 60.
What is the least common denominator for the fractions 3 and 9?
9 is.
Why do you need a common denominator?
Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.
What are the two new fractions that you will add together now that you have a common denominator?
They are equivalent fractions. For example, if you are adding 1/2 and 1/3 and the common denominator is 6, the two new fractions are 3/6 and 2/6 respectively.
How do you compare 3 or more fractions?
Find the equivalent fractions with the same denominator (the least common multiple) and then compare the numerators.
Two fractions have a common denominator of 8 what could the fractions be?
Any fractions with a denominator of 8. Also, the denominator of one of the fractions might be any factor of 8.
Is 1 a common denominator for the fractions 1 3 and 5 6?
No. The smallest common denominator is 6 .
What is the common denominator for 5 over 3?
At least two fractions are needed to determine a common denominator.
What is a vulgar fraction?
A fraction written with an integer numerator placed over a (nonzero) integer denominator is called a vulgar fraction. Vulgar fractions are also known as common fractions or simple fractions. Examples are 2/5 and 7/3. In those examples, the numerators are 2 and 7, the denominators are 5 and 3, all of which are integers. Simple/common/vulgar fractions are distinguished from compound fractions, from complex fractions, from mixed numerals, from decimal fractions, and from irrational fractions. Examples of fractions that are not common fractions are: * 0.75 -- decimal fraction * (3/4) / 2 -- complex fraction * (3/4) / (2/3) -- complex fraction * (1 1/2) / 2 -- complex fraction with mixed numeral in numerator * 3/4 of 5/7 -- compound fraction * 75% --- which equals 75/100, but written as a percent, it has neither a numerator nor a denominator * pi/4 -- irrational fraction. The distinction between common fractions and fractions that are not common is NOT the same as the distinction between proper fractions and improper fractions (which is explained below, but which is not needed to understand what a common fraction is). Common fractions can be either proper or improper. ------ If the absolute value of the numerator (the number on top) is less than the absolute value of the denominator (the number on the bottom) the fraction is called a PROPER fraction.. Examples are 2/3 and and -2/5. If the absolute value of the numerator is greater than the absolute value of the denominator (the number on the bottom) the fraction is called IMPROPER. Examples are 3/2 and and -5/2. Improper fractions can be converted to a mixed numeral, that is, an integer plus a fraction. For example 7/3 is equal to 2 1/3.
