Study Notes
Comparing Decimals
- Decimals represent parts of a whole, separated by a decimal point. The whole number part is before the decimal, and the fractional part is after. For example, in 3.45, '3' is the whole number and '45' is the fractional part.
Decimal Place Values
- Tenths: The first digit to the right of the decimal.
- Hundredths: The second digit to the right of the decimal.
- Thousandths: The third digit to the right of the decimal.
Steps to Compare Decimals
- Align the decimal points of the numbers you want to compare.
- Compare the digits in each place value, starting from the left.
- The first place where the digits differ shows which number is greater.
- If all the digits are the same, the numbers are equal.
Examples of Comparing Decimals
-
Example 1: Compare 0.35 and 0.37
- Align the decimals: 0.35 and 0.37
- Compare the tenths: same (3)
- Compare the hundredths: 5 < 7, therefore 0.35 < 0.37
-
Example 2: Compare 2.5 and 2.50
- Align the decimals: 2.50 and 2.50
- Compare the digits: They are the same, therefore 2.5 = 2.50
Common Mistakes to Avoid
- Forgetting to align the decimal points before comparing.
- Ignoring trailing zeros (e.g., 2.5 and 2.50 are the same).
- Comparing digits without considering their place value.
