3,2+2/15-0,8-2/5+2,9

To solve the expression \(3.2 + \frac{2}{15} - 0.8 - \frac{2}{5} + 2.9\), let's simplify it step by step.

1. Convert all terms to decimal where necessary:

   • \( \frac{2}{15} \approx 0.1333 \)
   • \( \frac{2}{5} = 0.4 \)

2. Now substitute the decimal values into the expression: \[ 3.2 + 0.1333 - 0.8 - 0.4 + 2.9 \]

3. Now combine the numbers step by step:

   • \( 3.2 - 0.8 = 2.4 \)
   • \( 2.4 - 0.4 = 2.0 \)
   • \( 2.0 + 2.9 = 4.9 \)
   • Finally, \( 4.9 + 0.1333 \approx 5.0333 \)

Thus, the final result is approximately: \[ \boxed{5.0333} \]
