Question

Multiply the decimal numbers.

$27.15\times 3.7$

Answer 1

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

$2715\times 37=100455$

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

$27\underline{.15}\times 3\underline{.7}$

In this case, we have $3$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.

$100\underline{.455}$

Therefore, $27.15\times 3.7=100.455$
