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.

Only if they are fractions in their simplified form.

3/4 750

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.

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

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.

it works when comparing fractions by multiplying the fractions to see whitch one is greater not greater and equal

The correct spelling is fractions instead of fractans. Comparing fractions means to tell which fraction is smaller and which is bigger.

Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).

RIGHT

It is easy: just convert to decimal fractions.
