Answer 2

Answer:

The correct answer is Option C: $4.03$

Step-by-step explanation:

Decimal multiplication:

1. To multiply decimals, multiply first as though there were no decimal.
2. Next, determine how many digits each factor has after the decimal.
3. Finally, add the same quantity of digits to the product's decimal place.

In many situations in daily life, using the multiplication operation on two numbers where at least one or both are decimal numbers is necessary.

$13*31=403$

Add two decimal points, hence : $1.3*3.1=4.03$
