How is adding mixed numbers different from adding fractions?
when you add mixed numbers you have a whole number but adding fraction does not.
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.
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
What two mixed numbers both add up to 30?
27.3 + 2.7
Do you Add both the numerators and the denominators when adding fractions and mixed numbers?
False [ I THINK ]
How do you estimate mixed numbers sums?
you have to add
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 can you add or subtract mixed numbers?

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.
