Question

Multiply the decimal numbers.

$1.1\times 3.0$

Answer 1

Step 1: Ignore the decimal point and multiply the decimal numbers with the usual multiplication.

$11\times 30$ $=330$

Step 2: Count the number of digits to the right of the decimal point in the decimal number.

$1\underline{.1}\times 3\underline{.0}$

In this case, we have $2$ digits after the decimal point.

Step 3: Put the decimal point in the product by counting the same number of digits from its rightmost place.

$3\underline{.30}$

Therefore, $1.1\times 3.0=3.30$
