2.84 has two numbers behind the decimal. - 8 and 4
31.29 has two numbers behind the decimal. - 2 and 9
when you multiply the numbers you get 888636.
now put 4 numbers behind the decimal and get 88.8636.
that is your answer. i only know of one way. im an engineer and dont know another way any simpler than this
The only way I know is to count the total number of decimals places in both numbers you are multiplying.
For example:
2.84
x 31.29
-------------
You multiply it, and then you place the decimal point after the 3rd number....because that's how many total places there are in the problem.
im sorry but your count is off. 4 decimal places would be behind the decimal.
Oh well...I am terrible at math. lol.
I have no idea what that means!
