Multiplying Decimals Practice

Train the one rule that runs all of decimal multiplication: multiply as if the numbers were whole, then count decimal places to position the point. Questions multiply numbers written in tenths (like 7.5 × 9.1), so answers land in the tenths or hundredths depending on how many decimal places the factors carry — counting them is the whole game.

The most common decimal-multiplication error isn't arithmetic, it's point placement — students compute 6825 correctly and then write 682.5. Instant feedback on every answer catches exactly that slip, and the count-the-places habit this drill builds is the same one scientific notation and percent calculations rely on later.
