Advanced Topics

Fractions and Decimals

Understanding Fractions

Fractions show parts of a whole. The top number (numerator) tells how many parts you have; the bottom number (denominator) tells how many parts make the whole.

Decimals

Decimals are another way to show parts of a whole, especially for money and measurements. The decimal point separates the whole number from the fractional part.

Comparing Fractions and Decimals

You can change fractions to decimals and vice versa. For example, \( \frac{1}{2} = 0.5 \).

Real-World Connections

Fractions and decimals are important in recipes, sports stats, and shopping!

Pro Tip

Always line up decimal points when adding or subtracting decimals.

Key Formula

\[\frac{a}{b} = decimal\]

Examples

  • 3/4 of a pizza is more than 1/2 a pizza.

  • 0.25 is the same as 1/4.
