-     4083 x 102 x 12 = 4997592. Sum of decimal places = 5         40.83 x 1.02 x 1.2 = 49.97592.    

Multiplication is a basic arithmetic operation in mathematics that is used to find the product of two or more numbers.

To multiply decimal numbers, we can follow these steps:

Multiply the numbers as if they were whole numbers, ignoring the decimal points.

Count the total number of digits to the right of the decimal point in the original numbers.

Insert the decimal point into the answer by starting from the right and counting as many digits as the total from step 2.

Applying this method to the given numbers, we get:

40.83

x 1.02

x 1.2

499.7592

There are 5 digits to the right of the decimal point in the original numbers (2 in 1.02 and 1 in 1.2, totaling to 3).

Starting from the right, we count 5 digits and insert the decimal point, giving us the final answer of 49.97592.

Therefore, the correct option is C, 49.97592.
