Example Questions
Example Question #42 : Adding And Subtracting Fractions
Add the fractions:
When adding fractions, the first thing we need to do is get a common denominator.
Then when adding, only add the numbers on the top, while leaving the common number on the bottom the same. Once we get a final answer, simplify accordingly.
Example Question #71 : Fractions
Add the fractions:
When adding fractions, the first thing we need to do is get a common denominator.
Then when adding, only add the numbers on the top, while leaving the common number on the bottom the same. Once we get a final answer, simplify accordingly.
Example Question #72 : Fractions
Add the fractions:
When adding fractions, the first thing we need to do is get a common denominator, but for this question, we do not need to do this because their denominators are already the same. Then when adding, only add the numbers on the top, while leaving the common number on the bottom the same. Once we get a final answer, simplify accordingly.
Example Question #73 : Fractions
Add the fractions:
When adding fractions, the first thing we need to do is get a common denominator.
Then when adding, only add the numbers on the top, while leaving the common number on the bottom the same. Once we get a final answer, simplify accordingly.
Example Question #74 : Fractions
Subtract the fractions:
When subtracting fractions, the first thing we need to do is get a common denominator.
Then when subtracting, only subtract the numbers on the top, while leaving the common number on the bottom the same. Once we get a final answer, simplify accordingly.
Example Question #75 : Fractions
Subtract the fractions:
When subtracting fractions, the first thing we need to do is get a common denominator.
Then when subtracting, only subtract the numbers on the top, while leaving the common number on the bottom the same. Once we get a final answer, simplify accordingly.
Example Question #76 : Fractions
Subtract the fractions:
When subtracting fractions, the first thing we need to do is get a common denominator.
Then when subtracting, only subtract the numbers on the top, while leaving the common number on the bottom the same. Once we get a final answer, simplify accordingly.
Example Question #49 : Adding And Subtracting Fractions
Combine the fractions and leave answer as either whole number or fraction.
First you must find the Least Common Denominator which is 28.
So you will multiply as follows to get the common denominator of 28:
Making it:
Combine to give answer:
Example Question #77 : Fractions
If 
Let's first write the equation out:
In order to add these fractions, we need to have a common denominator. To do this, we multiply the first term by the denominator of the second term, and vise versa:
Now we can add the numerators, while the denominators would stay the same:
We then simplify the numerator to get the final answer:
Example Question #51 : Adding And Subtracting Fractions
To add fractions, first find the common denominator. In this case, it's 21.
Then, multiply the numerators to get:
Then, add the numerators to get
