To solve
\(2 \cdot (2)/(3) + (1)/(5)\):

Convert
\(2 (2)/(3)\) to an improper fraction:
\(2 \cdot (2)/(3) = (8)/(3)\).

Add
\((8)/(3) + (1)/(5) = (43)/(15)\), or as a mixed number, \(2 (13)/(15)\).

let's solve
\(2 \cdot (2)/(3) + (1)/(5)\) step by step.

First, convert the mixed number to improper fractions:


\(2 \cdot (2)/(3) + (1)/(5)\)

To convert
\(2 (2)/(3)\) to an improper fraction, multiply the whole number (2) by the denominator (3) and add the numerator (2), then place it over the denominator:


\(2 \cdot (2)/(3) = (6)/(3) + (2)/(3) = (8)/(3)\)

Now the equation becomes:
\((8)/(3) + (1)/(5)\)

To add these fractions, find a common denominator, which is 15 in this case:


\((8)/(3) + (1)/(5)\)

Multiply the first fraction by
\((5)/(5)\) to make the denominators the same:


\((8)/(3) + (1)/(5) = (40)/(15) + (3)/(15)\)

Now add the fractions:


\((40)/(15) + (3)/(15) = (43)/(15)\)

Therefore,
\(2 \cdot (2)/(3) + (1)/(5) = (43)/(15)\)n, which as a mixed number is
\(2 (13)/(15)\).
