Multiplication

Problem:



Solution:

Step 1 - you do multiplication as normal, ignore the decimal point

  12
x 62
----
 72 
  24
----
 744

Step 2 - you count the number of digits after the decimal point.

There is one digit after the decimal point in 1.2
There is one digit after the decimal point in 6.2

Therefore in the product, we should have 1 + 1 = 2 digits after the decimal point, therefore the answer is 7.44
