Question

Multiply the decimal numbers.

$2.5\times 1.4$

Answer 1

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

$25\times 14=350$

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

$2\underline{.5}\times 1\underline{.4}$

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.

$3\underline{.50}$

Therefore, $2.5\times 1.4=3.50$
