convert both to numbers with lowest common denominator then 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.
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.
There is no answer because there are no mixed #.

No.

no
Yes
No.
yes
To find a sum for a mixed number you have to put the whole numbers aside and add them first, then you add the fraction part. If the denominators are different change them to the lowest common factor e.g 2 3/4 + 5 5/6 =2+5= 7 = 3/4 + 5/6= 3/12 + 5/12 = 7 8/12. I hope this helped!
