If you have two common denominators (the bottom number of the fraction), then all you have to do is add the top numbers and keep the bottom number the same and do not add them if the bottom numbers are the same. Ex1. 2/5 + 1/5 = 3/5
but also say if you have the two denominators the same but the numerators (top number of the fraction) equal the same as the denominator, then you now have a whole number which is always equal to 1. Ex2. 3/4 + 1/4= 4/4 = 1
Also another thing is if you have the denominators the same but when you add the numerators, and they equal a number over the denominator, this is called an improper fraction. Ex3. 2/3 + 2/3 = 4/3. after this happens, to make it into a proper fraction, you divide your denominator into your numerator and whatever is left over, you put over what you divided by.Ex4. 4/3 = 1 1/3. If you end up with a number that can be simplified (broken into its simplest form), you can either divide the denominator by the numerator, or you can divide each number by the biggest number they have in common. Ex5. 2/8 + 4/8 = 6/8 = 3/4 (if you divide each number by 2) If you get a fraction with it to be needing simplified, but is also an improper fraction, you first simplify it, then you make it into a mixed number ( Ex of mixed number = 1 2/3 ) Ex6. 5/8 + 7/8 = 12/8( divide by 4)= 3/2 = 1 1/2
Now that you have mastered that, we move on into unlike denominators. To find the denominator, you have to find the first number that each denominator has in common with each other. Ex7. 1/3 + 1/2 = 5/6. the first number that 2 & 3 had in common was a 6. So that is the number you always use. If you have the fraction needing to be simplified with unlike denominators, you first find their common number, then divide each number by the number that each has in common, but in this case, if it is already simplified, make it into a mixed number dividing the numerator by the denominator. Ex8. 1/2+ 2/3 = 7/6 = 1 1/6.

When adding or subtracting fractions what should you do first?
For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.
How do you check you math with adding fractions?
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
What is the rule for adding fractions?
They have to have a common denominator
How is adding fractions like adding whole numbers?
adding fractions is like adding a WHOLE lot of parts of numbers
How are adding fractions different?
When adding or subtracting fractions their denominators must be the same

How is adding mixed numbers the same as adding fractions?
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?
Before adding or subtracting two fractions they are converted into like fractions. Explain with examples why this is necessary.
How is adding like fractions and adding unlike fractions the same?
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.
How do you minnous fractions?
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.
