This is the background information on our project: We're gonna be adding and subtracting fractions. Here are different ways that you can add and subtract fractions: -- **With like denominators --** With different Denominators
 * and how to borrow from the whole number when you subtract also common&&lowest common denominators

__Adding&&Subtracting with like denominators__. 2/7 + 3/7 = 5/7 Its 5/7 because I just added the NUMERATORS and kept the same denominators. To make it more simple, if the denominators are the same and there are no whole numbers just add the numerators

5/6 + 4/6 = 5/6 + 4/6** =9/6 (6/6= a whole) 9/6 - 6/6 = 3/6 1 + 3/6 = 1 3/6 .. simplified to 1 1/2 cause i divided the N and D by 3

NOW WITH WHOLE NUMBERS .. 1 2/5 + 1 1/5 = 2/5 + 1/5 = 3/5 1 + 1 = 2 2 + 3/5 = 2 3/5

1 3/4 + 3 2/4 = 3/4 + 2/4 = 5/4 (4/4 a whole) 5/4 - 4/4 = 1/4 (*carry the whole number and added to the other whole numbers) 1 + 3 + *1 = 5 5 + 1/4 = 5 1/4 as you see here .. i showed you step by step on how i did that. I did the fractions first, then the whole numbers

__//now lets subtract..//__ 5/11 - 2/11 = 3/11 Its exactly the same as adding .. but im not adding .. im subtracting. Again, i just subtracted the numerators and kept the denominators.

NOW WITH WHOLE NUMBERS .. 3 3/5 - 1 1/5 = 3/5 - 1/5 = 2/5 3 - 1 = 2 2 + 2/5 = 2 2/5

5 1/4 - 2 3/4 = 1/4 - 3/4 = NOT POSSIBLE .. so you have to borrow the 5 turns into a 4 .. and 4/4ths are added to 1/4 so now the question is: 4 5/4 - 2 3/4= 5/4 - 3/4 = 2/4 4 - 2 = 2 2 + 2/4 = 2 2/4 as you see here .. i showed you step by step on how i did that. I did the fractions first, then the whole numbers

__Adding and Subtracting with different denominators__

common denominator: is ANY number that is a multiple of 2 or more numbers lowest common denominator (LCD): is a number that is the LOWEST common denominator of 2 numbers

e.g 2/6 + 2/4 one way to find a common denomninator is multiplying both denominators together 6*4 =24 2*4= 8 4*6 =24 2*6= 12

so its 8/24 + 12/24 = 20/24

another way we can do it is we find the multiples of the two numbers 2/6 + 2/4 4, 8, 12 6*2 =12 2*2= 4 4*3 =12 2*3= 6 4/12 + 6/12 = 10/12
 * 6,**12**
