49.95+21.95+19.95
Here let us try to add these three decimal numbers.
We can use Associative law of addition, which is :
(a+b)+c =a+(b+c)
Using the above law grouping first two numbers first,
(49.95+21.95)+19.95
Now adding first two numbers to get the result as:
=71.9 +19.95
After this point we can add these two numbers together,
=91.85
Answer is 91.85
