first u find a common denominator

When adding or subtracting fractions first make sure that the denominators are the same if they aren't then find the lowest common denominator and alter the fractions accordingly

Yes l

When you have a common denominator, the 2 fractions can be added by simply adding the numerators togethr and keeping the denominator. It might be harder to visualise this process without first getting a common denominator, thus having it might allow you to have a more accurate answer.

#1. when you are adding they are called addends #2. When you are subtracting they are called the first number is called a minuend and the second one is called a subtrahend #3. a sum is an answer to a addition problem #4. a difference is a answer to a subtraction problem

Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.

When adding or subtracting fractions with different denominators their lowest common denominator must be found first by using the LCM of their denominators

To subtract fractions with like denominators, subtract the numerators , and write the difference over the denominator. Example : Find 45−25 . Since the denominators are the same, subtract the numerators.

Same as for adding: If the denominators are not equal, you must first find a common denominator, then convert both fractions to that common denominator.

The first step to take is find the lowest common denominator of the fractions which can be done by finding the lowest common multiple of the numbers.

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).

3/83/4 - 3/8 = 6/8 - 3/8 = 3/8Always find the common denominator first when adding or subtracting fractions.
