Each place value is $10$ times smaller than the one to its left.

The correct statement is that each place value is $10$ times smaller than the one immediately to its left. For example, the ones place ($1$) is $10$ times smaller than the tens place ($10$), and the tenths place ($\frac{1}{10}$) is $10$ times smaller than the ones place ($1$). This is equivalent to saying each place value is $10$ times bigger than the one to its right.

• Saying it is $10$ times smaller than the one to its right is the reverse of the correct relationship.
• The relationship between adjacent places is a factor of $10$, not $100$.
• The place values are directly and systematically related.
