0,8-2/3+1/5

Let's compute the value step by step:

Given expression: 0.8 - 2/3 + 1/5

First, convert 0.8 to a fraction:
0.8 = 8/10 = 4/5

Now, rewrite the entire expression with fractions: 4/5 - 2/3 + 1/5

Find a common denominator for the fractions. The denominators are 5 and 3; the least common denominator (LCD) is 15.

Convert each fraction:

• 4/5 = (4 × 3) / (5 × 3) = 12/15
• 2/3 = (2 × 5) / (3 × 5) = 10/15
• 1/5 = (1 × 3) / (5 × 3) = 3/15

Now, combine the fractions: (12/15) - (10/15) + (3/15) = (12 - 10 + 3)/15 = (5)/15

Simplify: 5/15 = 1/3

Final answer:

\[ \boxed{\frac{1}{3}} \]
