Answer:
The answer is 1.632.
Explanation:
First, you multiply 3.2 by 1, which gives you 3.2. Then you move the decimal point one place to the left to get 0.32. You write this as 16.0 under the line and align the decimal points.
Next, you multiply 3.2 by 0.5, which gives you 1.6. You write this under the line and align the decimal points.
Then you add the two partial products: 16.0 + 1.6 = 17.6.
Finally, you count the number of decimal places in both factors: 3.2 has one decimal place and 0.51 has two decimal places, so the product has three decimal places. You move the decimal point three places to the left in the final answer to get 1.632.
