Key concepts students will learn:

  • When multiplying decimals, the first step is to remove the decimals from the problem and multiply as if they were whole numbers.

  • After multiplying, count the total number of digits behind the decimals in the original problem; your answer should have the same number of digits behind the decimal.

  • In the example, 5.21 × 3.8, there are three digits to the right of the decimal, so the final answer is 19.798.
