Question

Multiply the decimal numbers.

$2.4\times 4.8$

Answer 1

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

$24\times 48=1152$

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

$2\underline{.4}\times 4\underline{.8}$

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.

$11\underline{.52}$

Therefore, $2.4\times 4.8=11.52$
