Answer

To evaluate \( 0.09 \times 1000 \), follow these steps:

### Step 1: Understand the Decimal
The number \( 0.09 \) has two digits after the decimal point. This means it can be expressed as a fraction:
\[ 0.09 = \frac{9}{100} \]

### Step 2: Set Up the Multiplication
Now, we can set up the multiplication:
\[ 0.09 \times 1000 = \frac{9}{100} \times 1000 \]

### Step 3: Simplify the Expression
To simplify the multiplication, we can multiply \( 1000 \) by \( \frac{9}{100} \):
\[ \frac{9 \times 1000}{100} \]

### Step 4: Cancel Out the Common Factors
Now, we can simplify \( \frac{1000}{100} \):
\[ \frac{1000}{100} = 10 \]
So, the expression becomes:
\[ 9 \times 10 \]

### Step 5: Calculate the Final Answer
Now, we can calculate:
\[ 9 \times 10 = 90 \]

Thus, the final answer is:
\[ \boxed{90} \]
