find the vakue of the expression -4-5 1/3+(-5/2)

To find the value of the expression \(-4 - 5 \frac{1}{3} + \left(-\frac{5}{2}\right)\), follow these steps:

### Step 1: Convert the mixed number to an improper fraction
The mixed number \(5 \frac{1}{3}\) can be converted to an improper fraction:

\[
5 \frac{1}{3} = \frac{5 \times 3 + 1}{3} = \frac{15 + 1}{3} = \frac{16}{3}
\]

### Step 2: Rewrite the expression with fractions
The expression now becomes:

\[
-4 - \frac{16}{3} + \left(-\frac{5}{2}\right)
\]

### Step 3: Convert \(-4\) to a fraction with a common denominator
To add or subtract fractions, it's easier if they have the same denominator. Let's convert \(-4\) to a fraction with a denominator of 6 (the least common multiple of 3 and 2):

\[
-4 = \frac{-4 \times 6}{1 \times 6} = \frac{-24}{6}
\]

### Step 4: Convert all fractions to have a common denominator
Convert the other fractions to have the denominator 6:

- For \(\frac{16}{3}\), multiply both the numerator and denominator by 2:
  \[
  \frac{16}{3} = \frac{16 \times 2}{3 \times 2} = \frac{32}{6}
  \]

- For \(-\frac{5}{2}\), multiply both the numerator and denominator by 3:
  \[
  -\frac{5}{2} = \frac{-5 \times 3}{2 \times 3} = \frac{-15}{6}
  \]

Now the expression is:

\[
\frac{-24}{6} - \frac{32}{6} + \frac{-15}{6}
\]

### Step 5: Combine the fractions
Since all fractions have the same denominator, combine the numerators:

\[
\frac{-24 - 32 - 15}{6} = \frac{-71}{6}
\]

### Final Answer
The value of the expression is \(\frac{-71}{6}\).
