To multiply decimals, we multiply them just like whole numbers. We count the number of digits behind the decimal in both numbers we're multiplying, and make sure our answer has the same number of digits after the decimal. - We can check our answer by thinking about what it means to multiply by 0.5 (or one half).
When it comes to multiplying decimals, there's more than one way to get the job done. Explore different strategies in this unit and find the one that works best for you. From estimation, to area models, to grids, one of these is bound to help you master decimals multiplication.
