0,4*3 1/3=4,133

Let's calculate \( 0.4 \times 3 \frac{1}{3} \).

First, convert \( 3 \frac{1}{3} \) to an improper fraction:

\[ 3 \frac{1}{3} = 3 + \frac{1}{3} = \frac{9}{3} + \frac{1}{3} = \frac{10}{3} \]

Next, multiply \( 0.4 \) by \( \frac{10}{3} \):

\[ 0.4 = \frac{4}{10} = \frac{2}{5} \]

Now, multiply \( \frac{2}{5} \) by \( \frac{10}{3} \):

\[ \frac{2}{5} \times \frac{10}{3} = \frac{2 \times 10}{5 \times 3} = \frac{20}{15} \]

Now simplify \( \frac{20}{15} \):

\[ \frac{20}{15} = \frac{4}{3} \]

Now we convert \( \frac{4}{3} \) to a decimal:

\[ \frac{4}{3} \approx 1.3333 \]

Thus, the correct answer is:

\[ 0.4 \times 3 \frac{1}{3} = 1.3333 \text{ (or } \frac{4}{3} \text{)} \]

It seems that the value \( 4.133 \) in your statement is incorrect. The correct result is approximately \( 1.3333 \).
