3 6/5

But we cannot leave an improper fraction

3 + 1 1/5

4 1/5

Answer: 4 1/5


Step-by-step explanation:

Rewriting our equation with parts separated


=2 + 3/5 + 1 + 3/5


Solving the whole number parts


2 + 1= 3


Solving the fraction parts


3/5 + 3/5 = 6/5


Simplifying the fraction part, 6/5,


6/5 = 1 1/5


Combining the whole and fraction parts


3 + 1+ 1/5 = 4 1/5


Solution by Formulas


converting mixed numbers to fractions, our initial equation becomes,


13/5 + 8/5


Applying the fractions formula for addition,


=(13 × 5) + (8 × 5)/5 × 5


=65+40 / 25


=105/25


Simplifying 105/25, the answer is


=4 1/5
