Rules for Multippcation of a Decimal by a Whole Number

In the multippcation of a decimal number by a whole number, we first multiply the numbers by ignoring the decimal point.

We then put the decimal point before as many places in the product as there are in the decimal number.

Multiply 0.13 × 25

Solution

Step 1:

0.13 × 25

Multiplying without decimal point 13 × 25 = 325

Step 2:

The number of decimal places in 0.13 is two

The number of decimal places in 25 is zero

So the product has two decimal places, i.e., 3.25

Multiply 0.24 × 18

Solution

Step 1:

0.24 × 18

Multiplying without decimal point 24 × 18 = 432

Step 2:

The number of decimal places in 0.24 is two

The number of decimal places in 18 is zero

So the product has two decimal places, i.e., 4.32
