What does the term least common denominator mean?
In mathematics, the lowest common denominator or least common denominator (abbreviated LCD) is the least common multiple of the denominators of a set of fractions. It simplifies adding, subtracting, and comparing fractions.
In the set of rational numbers the complement of the set of integers is the set of fractions?
Only if they are fractions in their simplified form.
What is the rule for Equivalent Fractions?
3/4 750
How do you find the average fraction of a set of fractions?
First add all the fractions together. Then, divide this sum by the total number of fractions that were in the set. This quotient is your average fraction.
What is the rule in adding fractions having the same denominator?
Sum of the fractions = sum of numerators divided by their common denominator. Adding Fractions rule implies to addition of fractions having same denominator and as well as adding fractions with different denominators. So rule for adding fractions having the same denominator is add the numerators and simplify For example : 3/5 + 2/5 + 9/5 = (3 + 2 + 9)/5 [add the numerators] = 14/5
What are three rules you can use to compare fractions?
Rule #1 When two fractions have the same denominator, the bigger fraction is the one with the bigger numerator. Rule # 2 When comparing fractions that have the same numerator, the bigger fraction is the one with the smaller denominator. Rule # 3 You can convert the fractions and then just put the greater than, less than or equal to sign to see what the comparison is between the fractions.
Why does the butterfly method work when comparing fractions?
it works when comparing fractions by multiplying the fractions to see whitch one is greater not greater and equal
What does comparing fractans mean?
The correct spelling is fractions instead of fractans. Comparing fractions means to tell which fraction is smaller and which is bigger.
What is the name for fractions that are commonly used for comparing measuring and estimating?
benchmark fractions
Explain how comparing fractions with like denominators differs from comparing fractions with unlike denominators?
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).

What do you do when comparing fractions and the denominator and the numerator are different?
Convert them into equivalent fractions with the same denominator and then compare the numerators.
When comparing fractions with the same you only have to compare the?
Numerator, Denominator or Denominator, Numerator.
