When u multiply a whole number by 10 ,what is always true about the ones place in the product

The one's place is always zero.

What is always true about the ones place in the product

When you multiply a whole number by 10, the ones place in the product will always be zero.

When you multiply a whole number by 10, the number in the ones place of the product will always be 0.

To understand why this is true, let's consider the concept of place value. In our decimal number system, each digit in a number represents a different place value. The rightmost digit is the ones place, the next digit to the left is the tens place, then the hundreds place, and so on.

Multiplying a number by 10 essentially means increasing its value by one place to the left. For example, if you multiply 5 by 10, you move the 5 from the ones place to the tens place, resulting in 50. Similarly, if you multiply 123 by 10, you move each digit one place to the left, resulting in 1230.

Regardless of the original number you start with, when you multiply it by 10, the number in the ones place will never contribute to the final product. This means that the ones place will always be filled with a 0. So, it is always true that the ones place in the product will be 0 when you multiply a whole number by 10.
