How Do You Multiply Numbers by Whole Tens?
FAQs on Multiply Whole Tens: Grade 4 Maths Practice Worksheet
1. How do you multiply by whole tens?
To multiply whole tens, you first multiply the non-zero digits and then add the total number of zeros from both numbers to the end of the product. This method simplifies the multiplication of tens and is a key concept in Grade 4 maths multiplication.
- Step 1: Identify the numbers without the zeros (e.g., in 30 × 40, the numbers are 3 and 4).
- Step 2: Multiply these base numbers (3 × 4 = 12).
- Step 3: Count the total number of zeros in the original numbers (one in 30, one in 40, so two zeros).
- Step 4: Add these zeros to your result (12 becomes 1200).
