Answer explanation

To multiply a one-digit whole number by a multiple of 10 or 100, follow these simple steps:

1. Identify the Numbers: For example, let's say you have 5 (the one-digit number) and 60 (a multiple of 10).

3. Multiply the One-Digit Number: First, multiply the one-digit number by the number in front of the zeroes. For 5×6, you get 30.

5. Add the Zeros: Since 60 has one zero, you will add one zero to your answer. So, 30 becomes 300.

7. For Multiples of 100: If you’re multiplying by a multiple of 100, like 400, just add two zeros. For example, 5×4=20, and then add two zeros to get 2000.
