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.

Yes, but the numerator is different,same as adding fractions

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.

You basically have to learn separately how to do different things with fractions, including finding a common denominator; converting fractions to a different denominator; simplifying fractions; adding and subtracting fractions; multiplying fractions; dividing fractions.

when you add mixed numbers you have a whole number but adding fraction does not.

You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent fractions.

When adding or subtracting fractions with different denominators and when reducing fractions to their lowest terms

When adding or subtracting fractions with different denominators and when reducing fractions to their lowest termsWhen adding or subtracting fractions with different denominators their lowest common multiple is needed and when reducing fractions to their lowest terms their greatest common factor is needed.

adding fractions is like adding a WHOLE lot of parts of numbers

Ensure that the denominators are the same when adding or subtracting fractions.

When adding or subtracting fractions with different denominators and when reducing fractions to their lowest terms.

Dissimilar fractions have different denominators and their lowest common denominator must be found in order to add them up.

A common denominator is needed when adding or subtracting fractions of different denominators.

Similarities: the sum does not depend on which number you start with (distributive)Differences: you must find a common denominator for the fractions (whole numbers have a common denominator [1]

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

The denominators must be the same, the numerators can be different.

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

Mixed numbers can be converted to improper fractions. Then, it is exactly the same as adding proper ones.

Before adding or subtracting two fractions they are converted into like fractions. Explain with examples why this is necessary.

When adding or subtracting fractions with different denominators the LCD is found with the LCM.

When adding or subtracting fractions with different denominators

For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.
