@luvbeingmama83 You don't. He just dropped the trailing zero because 2.70 is the same as 2.7. You just remove both decimals and treat the problem as 146 * 27 = 3942, then move the decimal to the left twice, which returns 39.42.

I thought with multiplication you dont need to line up the decimals before you start the problem

Are you seriously criticizing this guy for helping you better yourself, and understanding of Mathematics ?
You obviously needed help, and he's taking the time out of his day to provide it for free.

It should be Multiplying Decimals 3. NOT muLITplyling. Minor typo.
