First, convert each fraction to an improper fraction


Let's convert into an improper fraction:

Mixed Fractions to Improper Fractions


Remember, mixed fractions (or mixed numbers) are of the form:


               numerator
whole part ----------------
              denominator

So we can see that: , , and

Now follow these steps to convert the mixed fraction to an improper fraction

Step 1) First, multiply the whole part by the denominator to get .

Step 2) Now add that result to the numerator to get . This result is the new numerator. The denominator will remain the same.

Step 3) Place the new numerator over the original denominator to get

Now let's add

Solved by pluggable solver: Fractions Solver


Start with the given expression




In order to add these two fractions, these fractions need to have a common denominator.


In order to do that, we simply find that the LCM of 4 and 8 is 8 (note: if you need help with finding the LCM, check out this solver)


Now we need to get each denominator to 8



Multiply by


Multiply and to get



Since both fractions have a common denominator of 8, we can now combine the fractions


Combine the fractions


Add the numerators



So







Finally, convert back to a mixed fraction

2 3/4 + 1 1/8

Here's a better way. Start by writing one fraction under
the other and drawing a line underneath:

2 3/4
1 1/8
--------------

Get a common denominator of 8 and rewrite the fraction
parts with the common denominator:

 2 3/4 = 2 6/8 
+1 1/8 = 1 1/8
--------------

Add the whole parts and the fraction parts:

 2 3/4 = 2 6/8 
+1 1/8 = 1 1/8
--------------
         3 7/8

That's the answer in this case, but sometimes the fraction
part is top heavy (improper) and you have go another step.
[Also when you do subtraction this way, sometimes you have
to borrow from the whole part to make the top fraction bigger
than the bottom fraction.)
