FAQ
How do students determine where to place the decimal in the product?⌄
Count the total decimal places in both factors — a 1-digit decimal has one decimal place, so the product also gets one decimal place from the right.
How does this multiplication relate to repeated addition?⌄
Multiplying 4 × 0.7 is the same as adding 0.7 four times (0.7 + 0.7 + 0.7 + 0.7), which helps students verify their answers conceptually.
What common mistake should students avoid when multiplying a whole number by a decimal?⌄
Forgetting to count decimal places in the product — treating the multiplication like a whole number problem and placing no decimal point — is the most frequent error.
