Convert into a decimal:
`3(3)/(5)`

Answer

To convert the mixed fraction \(3 \frac{3}{5}\) into a decimal, follow these steps:

### Step 1: Convert the mixed number to an improper fraction.
A mixed number consists of a whole number and a fraction. To convert it to an improper fraction, we multiply the whole number by the denominator and add the numerator.

\[ 3 \frac{3}{5} = \frac{(3 \times 5) + 3}{5} \]

### Step 2: Calculate the numerator.
Now, calculate \(3 \times 5\):

\[ 3 \times 5 = 15 \]

Then, add the numerator (which is 3):

\[ 15 + 3 = 18 \]

So, we have:

\[ 3 \frac{3}{5} = \frac{18}{5} \]

### Step 3: Divide the numerator by the denominator.
Now, we need to divide \(18\) by \(5\) to convert the improper fraction to a decimal:

\[ 18 \div 5 = 3.6 \]

### Final Answer:
Thus, the decimal form of \(3 \frac{3}{5}\) is \(3.6\).
