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

When adding or subtracting fractions their denominators must be the same

Adding fractions is achieved by adding the numerators as long as the denominators are the same. When the denominators are the same the fractions are "like fractions". With different denominators they are "unlike fractions"; to be able to add them they need to be converted in to equivalent fractions with the same denominators. They are then "like fractions" and can be added.

When adding unlike fractions, find the lowest common denominator, convert them to like fractions and proceed with the addition.

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.

Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

adding fractions

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

first must find Least Common Denominator http://www.loisterms.com/lois21.htm First of all, if you want to know about adding fractions, check out "How to Add Fractions". Be sure to follow the math examples carefully. To subtract fractions, follow the same steps as for adding, except subtract where you would add. Now about those positive and negative signs. The rules are the same whether you are working with integers or fractions. I will give you a method of learning the rules for the signs that has worked for many other students. Copy off this "Rules for Integers" chart and paste it on a large index card. Put the card in your math book or folder and refer to it often while you are doing your homework. If you keep using the card, you will get better with the signs.

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

If their denominators are different then find their lowest common denominator by means of their lowest common multiple remembering to adjust their numerators accordingly before adding or subtracting.

Yes, you must.

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

adding fractions r easy math prblems. like 1/4 +1/4 = 1/2.

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.

Adding like terms can be like adding fractions. You can only add fractions with a common denomonator. You can only combine terms together if they are like. Think of like terms as denomonators. You can only add if they are like.

You need a common denominator for both.

They have to have the same denominator.

When adding fractions, you want to make sure that the denominators are the same. It's the same process as the LCM.

Subtracting a fraction is the same as adding its negative.

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
