Different denominators: First, you find a common denominator (it can be the least common denominator, or any common denominator), and convert all fractions involved to equivalent fractions, using the common denominator. For example, 1/4 + 2/3. 12 is a common denominator; you can write this as 3/12 + 8/12.Same denominator: Just add (or subtract) the numerators, and keep the denominator. The above addition would become 11/12.
Finally, you may want to check whether you can simplify the answer. Depending on how you (or the teacher) prefers the answer, you may also want to convert to a mixed fraction. In the above example, no such simplification is possible.

What are unlike mixed numbers?
the fractions have different denominators
How do you subtract fractions with mixed numbers and like denominators?
Convert them to improper fractions and proceed.
How do you add mixed fractions with different denominators?
You make it into a improper fraction, then make a common denominator and remember to do what you did to the bottom to the top then solve
How do you subtract mixed number to mixed number?
Convert them to improper fractions with common denominators and proceed normally.
Adding mixed numbers with unlike denominators?
First convert the mixed numbers into "top heavy (or "improper) fractions". Now multiply each of the improper fractions by each other - this makes the denominators the same. Now you can add both the fractions together (and cancel down if necessary).
What is a fraction or mixed number whose denominators are powers of 10?
Although fractions or decimals are not called this, they are, in fact, decimal fractions.
Do you Add both the numerators and the denominators when adding fractions and mixed numbers?
False [ I THINK ]
How to add and subtract mixed numbers?
Convert them to improper fractions with common denominators and proceed.
How do you add mixed numbers with different denominators?
First convert them t top-heavy fractions. Treat these as you would ordinary fractions: find common denominator and so on. At the end, convert the top heave fraction back to a mixed fraction.
How do you add mixed fractions with another mixed fraction?
You convert them both to improper fractions by multiplying the denominators by the whole number and then adding the numerator to it. This number goes in the numerator and the denominator stays the same. Then you do this for the other fraction, making sure that the denominators of each fraction are equivalent. Then add the fractions as normal.
What is the first thing you should look for when adding or subtracting fractions or mixed numbers?
common denominators.
When asked to find the sum of two mixed numbers with different denominators you should before you add?
Convert the fractions into equivalent fractions with the same denominator. In actually adding mixed numbers, it is easier to convert the mixed numbers into improper (top heavy) fractions, do the addition, simplify the resulting fraction and convert any resulting improper fraction back into a mixed number.
