Answer:

In multiplication of a decimal by a decimal number we will learn how to find the product of a decimal by another decimal.

To multiply a decimal number by a decimal number, we first multiply the two numbers ignoring the decimal points and then place the decimal point in the product in such a way that decimal places in the product is equal to the sum of the decimal places in the given numbers.

The rules to multiply a decimal by a decimal are:

(i) Remove the decimals of the two numbers and then take the two numbers as whole numbers and multiply.

(ii) In the product, place the decimal point after leaving digits equal to the total number of decimal places in both numbers.

(iii) Counting must always be done from the units place of the product.

Let us consider some of the following examples on multiplication of a decimal number by a decimal number.

1. Find the product of 1.2 × 1.2

First we will perform the multiplication ignoring the decimal points in multiplicant and multiplier.

Multiplication of a Decimal by a Decimal

Since 12 × 12 = 144

Now place the decimal point in the product to give as many decimal places in the product as there are in the multiplicant and the multiplier together.

Therefore, 1.2 × 1.2 = 1.44
