Question

Multiply the decimals.

$2.6\times 12.3$

Answer 1

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

$26\times 123$ $=3198$

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

$2\underline{.6}\times 12\underline{.3}$

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.

$31\underline{.98}$

Therefore, $2.6\times 12.3=31.98$
