Answer
40.902
Work Step by Step
To multiply decimals, imagine that there no decimals included in the number. Momentarily erase the decimals and multiply.
It now looks like we are multiplying 102 x 401, which equals 40, 902.
Now, we can look at our original problem. Our original problem had a total of three numbers located behind the decimal: .2 in 10.2 and .01 in 4.01.
As there were three decimals in our original problem, we must move the decimal from our product three places in:
40,902.00
Move the decimal three places to the left and the number becomes:
40.902
This is the final answer.
