UNLIKE DENOMINATOR is a fraction with an unequal bottom number.
For example: 4 1/6 - 1 3/4=?
step 1: Deal with fractions use L.C.M.(lowest Common Multiple) to create common denominator.
6- 6,12,18,24,30
4- 4,8,12,16,20
The lowest common multiple of 4 and 6 is 12.
step 2: Make an equivalent fraction.
1/6= 2/12 3/4=9/12
You cannot subtract 2 and 9. So, I barrow from the whole numbers.
2/12 - 9/12= 12/12 + 2/12 - 9/12= 5/12
step 3: Deal with the whole numbers.
3-1=2
step 4: combine the fraction and the whole number.
answer: 2 5/12

Adding Mixed Numbers With Unlike Denominators
Here's a QUESTION FOR EXAMPLE:
6 3/8 + 7 3/16
STEP 1: Look for the L.C.M (lowest common multiple) 8-8, 16-------16-16
STEP 2: Make equivalent with this... 3/8= 6/16---------3/16=3/16
STEP 3: Deal with the FRACTIONS .....6/16 + 3/16 = 9/16
STEP 4: Deal with the WHOLE NUMBERS 7+6=14
STEP 5: Combine! 14 9/16
GET IT???!!!

Adding Mixed Numbers With Like Denominators
If You Forgot What's a Mixed Number : A mixed number is made up of a whole number and a fraction Such as : 6 1/2 This is NOT mixed number 6 9/3
Here's a QUESTION FOR EXAMPLE: 9 3/6 + 3 1/6=?
STEP 1: Deal with the FRACTION THAT ALREADY HAVE COMMON DENOMINATORS!! Simplify too!!
3/6+1/6= 4/6= 2/3
STEP 2 : Deal With the WHOLE NUMBERS
9+3=12
STEP 3 : Combine them together!!
12 2/3
Get it??!?
