Solution

Step 1: Initially, ignore the decimal point and multiply the two numbers normally.

811×1032433+00008110083533

Step 2: After multiplication, count the total number of decimal places in both the numbers. The product obtained after multiplication will have this total number of decimal places. Number of decimal places in each decimal number is as shown below,

81.111.032

Here the total number of decimal places is 3.

Step 3: Place the decimal point in the obtained product following Step 2. Here 3 decimal point has to be placed in obtained product 83.533

Hence, by multiplying 81.1 by 1.03 we get 83.533.
