Find the product :
`0.028 xx0.9`

Answer

To find the product of \(0.028\) and \(0.9\), we can follow these steps:

### Step 1: Ignore the decimal points
First, we will ignore the decimal points and multiply the numbers as if they were whole numbers.
So, we will multiply \(28\) (from \(0.028\)) and \(9\) (from \(0.9\)).

### Step 2: Multiply the whole numbers
Now, we calculate \(28 \times 9\):
\[ 28 \times 9 = 252 \]

### Step 3: Count the total number of decimal places
Next, we need to determine how many decimal places are in the original numbers:
- \(0.028\) has 3 decimal places.
- \(0.9\) has 1 decimal place.

Adding these together gives us:
\[ 3 + 1 = 4 \text{ decimal places} \]

### Step 4: Place the decimal point in the product
Now, we take the product \(252\) and place the decimal point to have a total of 4 decimal places:
\[ 252 \rightarrow 0.0252 \]

### Final Answer
Thus, the product of \(0.028\) and \(0.9\) is:
\[ \boxed{0.0252} \]
