adding fractions is like adding a WHOLE lot of parts of numbers
When adding or subtracting fractions their denominators must be the same
Ensure that the denominators are the same when adding or subtracting fractions.
What is the definition of Adding and Subtracting Like Fractions
Mixed numbers can be converted to improper fractions. Then, it is exactly the same as adding proper ones.
For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.
Yes, you must.
Before adding or subtracting two fractions they are converted into like fractions. Explain with examples why this is necessary.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
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.
You need a common denominator for both.
They have to have the same denominator.
When adding or subtacting fractions make sure that the denominators are of the same values if they are not then find the lowest 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

Subtracting a fraction is the same as adding its negative.
