Adding Fractions
A Proper Fraction
I can...
I can subtract fractions with the same denominator.
I Can...
I can multiply a one digit fraction x a one digit fraction.
By The Math Pack
A proper fraction has a denominator that is larger than its numerater.
(ThreeEighths)
3/8
Example
8
9
A proper fraction can be written in many diffrent ways. As long as the shaded part of the fraction (the numerater) is less then the whole (the denominater) than it is a proper fraction.
Example
Improper Fraction and Mixed Numbers
A improper fraction has a numerater that has greater amount then its denominator. It is basicly
Example
9
8
This improper fraction are qivelent because 8 goes into 9 one time and you have 1/8 left so you put that right next to your whole number now you have,

Now we can get into adding, multiplying, dividing, and subtracting fractions.
When adding Fractions, you need to of course have the same denominators. But where not going to get in to that lets just add fractions.
Also, you never and the denominators of fractions, just the numeraters.

So the sum of this fraction is, 5/9.
I can statement...
I can add fractions that have comman denomanators
When subtracting fractions you will NOT subtract your denominators, you only subtract your numeraters. Just like adding your fractions.

You also need your bigger fraction first (in this case you would put 7/9 first) then you would start to subtract your fractions.

Fraction
A fraction consist of a numerator (the top number) and a denominator (the bottom number)
Example
8
10
Your denominator always has to be larger then your numerator.
Not in size, in value

Mixed Number
A mixed number is a whole number that has a fraction to the right of it.

Improper Fraction

Common Denominator
There are 3 Simple Steps to add fractions:
•Step 1: Make sure the bottom numbers (the denominators) are the same (common denominators)
•Step 2: Add the top numbers (the numerators), put the answer over the denominator
•Step 3: Simplify the fraction (if needed)
Means that to fraction that you are comparing have the same denominators or the denominators are equal.

When Multiplying Fractions, you multiply your denominators and your numeraters.
And your denominotors don't have to be the same.
There are 3 simple steps to multiply fractions
1. Multiply the top numbers (the numerators).
2. Multiply the bottom numbers (the denominators).
3. Simplify the fraction if needed.

Multiplying Fractions By A Whole Number
Adding And Subtracting Fractions
You can also very easily convert a improper fraction to a mixed number. By,
Seeing how many times the denominator can go into the numerater of the fraction that you are trying to convert.
Next, put the number of times the denominator can go into the numerater where you need to put the answer (like a answer line).
17
10
10 can only go into 17 one time because 1710=7 so you would have a remainder (will use that later)
1
Then see what is left after you subtract. So in this case, we already subtracted to see what are whole number was. Now we need to figure out what our fraction is.
The way we find this out is, by seeing what our remainder is when we were finding out the whole number. So, 1710=7 We need the seven.
Now, what you do in this situation is: put the remainder over the denomonator that you had in your improper fraction to start off. The Improper fraction 17/10 equals 1 7/10
