### How do you add a mixed fraction by a mixed fraction?

You can either add the fractional parts and, if required, convert the answer to a mixed fraction and then add the integer part to the integer parts of the two original numbers; or change both numbers to top-heavy (or improper) fractions, add them and then convert the answer to a mixed fraction.

when you add mixed numbers you have a whole number but adding fraction does not.

### When can you add or subtract mixed numbers?

You can always do that.

### How do you add mixed numbers together?

just find a common denominator and add the two numerators together then add the whole numbers

### How do you add multiple mixed fractions?

Find a common denominator, add the numerators, simplify if possible.

### Do you need to get the LCM of mixed numbers?

Only to add, subtract, or compare two fractions. Note: Technically, to add two fractions (for example) you don't need the LEAST common multiple; any common multiple will do. As an example, if you want to add 1/4 + 1/6 (or any mixed number that ends with this fraction), you can use 24 as a common denominator (you can obtain this by multiplying 4 x 6), even though the least common multiple is 12.To add two mixed fractions, the easiest way is usually to add the whole part and the fractional part separately.

### How do you find the sum of two mixed numbers?

To find the sum of two mixed numbers, turn the mixed numbers into improper fractions (multiply the base with the denominator and add the numerator), then add the two fractions. To add the two fractions, find the LCD (lowest common denominator) and add the two numerators, but leave the denominators the same.

### How do you add mixed numbers with whole numbers?

To add mixed numbers and whole numbers, you simply treat the mixed numbers like they are whole numbers (4 3/4) turns to (4), then add the regular whole number, say, 7, and then re-add the fraction. For example, if you were adding 4 3/4 and 7, you would change 4 3/4 to 4, add 7 to get 11, then add the 3/4 back in, to give you 11 3/4.

### How can you add and subtract mixed numbers?

Make it into an both numbers an improper fraction and then do the opperation.

### How would you add two mixed numbers together if they have different denominators that don't go into each other?

Find the least common multiple. For example, if the denominators were 6 and 7, the least common multiple would be 42.

### When can the sum of two mixed numbers be a whole number?

2 mixed numbers can only be a whole when the 2 numerators add up to the number
