Explanation: The best way to understand decimals is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

Find the product of 6.412 \$\times\$ 33.2.

Step 1a

The given numbers are 6.142 and 33.2.

Multiply the numbers as whole numbers by removing the decimal point.

$1a$

Explanation: In this step, we arrange the numbers. Now ignore the decimal point and multiply the two numbers following the regular multiplication method i.e., \$6142 \times 332 = 2039144\$.

Step 1b

After multiplying two numbers, count the total number of decimal places.

The product will have the same number of decimal places.

$1b$

Explanation: In this step, determine the decimal places in each number by counting the digits to the right of the decimal point. For 6.412, there are 3 decimal places, and for 33.2, there are 2 decimal places.

Therefore, the total decimal places are 4. 6.142 × 33.2 = 203.9144.
