How we explain it

Children can open this short lesson before they practice.

  1. Multiply as if there were no decimal points.
  2. Count the decimal places in the numbers you started with.
  3. Give your answer that many decimal places.

Example: 0.6 × 4 = ? Ignore the point: 6 × 4 = 24. 0.6 has 1 decimal place. So the answer has 1 decimal place: 2.4. Answer: 2.4
