Decimal Multippcation: Problem Type 1

Decimal multippcation is done in a similar way as whole number multippcation.

Rules for Decimal Multippcation

First we multiply the decimal numbers as if they were whole numbers by ignoring the decimal points.

Here the decimal points are not pned up vertically as in addition and subtraction. Here the digits are pned up to the right.

The number of digits after the decimal point in both the numbers are counted and added.

In the final product, a decimal point is placed before that many digits from the right.

Multiply 13.4 × 0.35

Solution

Step 1:

13.4 × 0.35

We pne up the digits and not the decimal points

We now multiply the numbers by ignoring the decimal points and assuming as if they were whole numbers.

Step 2:

13.4 has one decimal place. 0.35 has two decimal places. So the product of these numbers has three decimal places.

Multiply 16.5 × 0.27

Solution

Step 1:

16.5 × 0.27

We pne up the digits and not the decimal points

We now multiply the numbers by ignoring the decimal points and assuming as if they were whole numbers.

Step 2:

16.5 has one decimal place. 0.27 has two decimal places. So the product of these numbers has three decimal places.
