Find the product :
`1.2xx3.5xx0.3`

Answer

To find the product of 1.2, 3.5, and 0.3, we can follow these steps:

### Step 1: Multiply the first two numbers (1.2 and 3.5)
- Ignore the decimal points initially and multiply 12 by 35.

\[ 12 \times 35 \]

### Step 2: Calculate 12 times 35
- Break it down:
- \( 12 \times 35 = 12 \times (30 + 5) = 12 \times 30 + 12 \times 5 \)
- \( 12 \times 30 = 360 \)
- \( 12 \times 5 = 60 \)

Now add these two results:

\[ 360 + 60 = 420 \]

### Step 3: Multiply the result with the third number (0.3)
- Now take the result from Step 2 (420) and multiply it by 0.3.
- Again, ignore the decimal point initially and multiply 420 by 3.

\[ 420 \times 3 \]

### Step 4: Calculate 420 times 3
- Perform the multiplication:

\[ 420 \times 3 = 1260 \]

### Step 5: Count the total number of decimal places
- Now we need to consider the decimal places from the original numbers:
- 1.2 has 1 decimal place.
- 3.5 has 1 decimal place.
- 0.3 has 1 decimal place.

Total decimal places = 1 + 1 + 1 = 3.

### Step 6: Place the decimal in the final product
- The product we calculated is 1260. Since we have 3 decimal places, we place the decimal point three places from the right:

\[ 1260 \rightarrow 1.260 \]

### Final Answer
The product of 1.2, 3.5, and 0.3 is **1.260**.
