2. If a whole number is divided into 10 equal parts, then each part is called one-tenth of a unit and written

as \(\frac{1}{10}\) and 0.1 in decimal notations.

3. If a whole number is divided into 100 equal parts, then each part is called one-hundredth of a unit and written as \(\frac{1}{100}\) and 0.01 in decimal notation.

4. In standard form, the decimal is always put between the unit place and tenths-place.

5. In the place value chart, as we go from left to the right, the multiplying factor becomes factor \(\frac{1}{10}\) of the previous factor.

For example: 0.23, 1.26, 3.65 are all like decimals.
