2/3+5/3=2,333

Let's break down the addition of the fractions \( \frac{2}{3} + \frac{5}{3} \).

1. Since both fractions have the same denominator (3), you can add the numerators together: \[ \frac{2 + 5}{3} = \frac{7}{3} \]

2. Now, convert \( \frac{7}{3} \) to a decimal: \[ \frac{7}{3} \approx 2.3333... \]

So, your calculation is correct: \( \frac{2}{3} + \frac{5}{3} = \frac{7}{3} \approx 2.333 \).

Therefore, \( 2/3 + 5/3 = 2.333 \) is accurate.
