Add the numerators of the two fractionsPlace that sum over the common denominator.If this fraction is improper (numerator larger than or equal to the denominator) then convert it to a mixed numberAdd the integer portions of the two mixed numbersIf adding the fractional parts created a mixed number then add its integer portion to the sum.Example: 3 2/3 + 5 2/3 =
Add the fractional part of the mixed numbers2/3 + 2/3 = 4/3
Convert 4/3 to a mixed number 4/3 = 1  1/3
Add the integer portions of the mixed numbers 3 + 5 = 8
Add the integer from the sum of the fractions 8 + 1 = 9
State the final answer:9  1/3

first make sure that the both of them are similar fractions. If they are not similar fractions make it to similar fractions. Then add the numerator. Add the whole numbers too. If it is a improper fraction, turn it unto proper fraction
ex.
   8  9/10 + 7 5/9 = N
   8  N/90 + 7 N/90 =N
   90 ÷ 10= 9 × 9 = 81 so it becomes 8 81/90 + 7 N/90
   90 ÷ 9 =10 × 5 = 50 so it becomes 8 81/90 + 7 50/90
   81 + 50 = 131
   8 + 7 = 15
   so it becomes 15 131/90
   must be proper fraction so...
   131 
÷ 90= 1.41
    add the whole number to the whole number...  15 + 1= 16 then make the decimals as the numerator... so it becomes
        16 41/90 !!!
