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 is the rule for subtracting fractions?
First, change it so that the two fractions have the same denominator (by changing the fractions into equivalent fractions). Once the two fractions have the same denominator, it is simply a case of subtracting the numerators, leaving the denominator the same. Finally, reduce the fraction to its lowest terms (if possible).
What is a general rule for multiplying fractions and whole numbers?
A general rule for multiplying fractions: You shall not multiply the denominator by the whole number,only the numerator.Another rule is you shall make the whole number as a fraction by putting the whole number as the numerator and 1 as the denominator before multiplying it.
Do the adding fractions rule apply to subracting?
Yes inasmuch that the denominators of the fractions must be common to each other.
What is the rule of adding and subtracting different denominator?
Find the lowest common denominator by finding the lowest common multiple of the denominators
What is a rule for ordering fractions with the same denominator?
If they have the same denominator, then (assuming the denominator is positive), igbore the denominator for determining the order. That is, order the numbers by their numerators. In the unlikely event that the denominator is negative, the above method will give the reverse order.
