What Are Decimals? π’
A decimal is a number that represents a fraction of a whole, typically separated by a decimal point. For instance, in the number 3.75, "3" is the whole number, and ".75" represents seventy-five hundredths. The placement of digits to the right of the decimal point indicates their values:
Place Value | Decimal Places | Value |
---|---|---|
Ones | 0.0 | 3 |
Tenths | 0.1 | 0.7 |
Hundredths | 0.01 | 0.05 |
Comparing Decimals π
When comparing decimals, the following steps can guide you:
- Align the Decimals: Write the decimals in a vertical format so that the decimal points line up.
- Compare from Left to Right: Start comparing from the leftmost digit and move towards the right.
- Determine the Larger Number: The decimal with the larger digits at the first point of difference is greater.
For example, when comparing 0.75 and 0.8:
0.75
0.80
- The first digit after the decimal is the same (7 and 8).
- The second decimal of 0.75 is smaller than 0.80, thus 0.75 < 0.80.
