๐Ÿ”ข Quick Study Guide: Decimals - Tenths & Hundredths

  • ๐Ÿ’ก Understanding Decimals: Decimals are a way to represent numbers that are not whole. They use a decimal point to separate the whole number part from the fractional part.
  • ๐Ÿ” Place Value to the Right: Digits to the right of the decimal point represent fractional parts. The first digit is the 'tenths' place, and the second digit is the 'hundredths' place.
  • โœ–๏ธ Tenths ($0.1$): The tenths place represents divisions of a whole into 10 equal parts. For example, $0.7$ means 'seven tenths', which is equivalent to $\frac{7}{10}$.
  • ๐Ÿ’ฏ Hundredths ($0.01$): The hundredths place represents divisions of a whole into 100 equal parts. For instance, $0.25$ means 'twenty-five hundredths', equivalent to $\frac{25}{100}$.
  • ๐Ÿ—ฃ๏ธ Reading Decimals: Read the whole number part (if any), say 'and' for the decimal point, then read the digits after the decimal point as a whole number, followed by the place value of the last digit. E.g., $0.03$ is 'three hundredths'.
  • โ†”๏ธ Converting Fractions: To convert a fraction with a denominator of 10 or 100, simply write the numerator in the correct decimal place value. Example: $\frac{9}{10} = 0.9$ and $\frac{13}{100} = 0.13$.
  • ๐Ÿง Comparing Decimals: To compare decimals, align the decimal points and compare digits from left to right. You can add trailing zeros without changing the value to make comparison easier (e.g., $0.5 = 0.50$).
