Pre-Algebra introduces foundational concepts in mathematics, including integers, fractions, and basic equations, essential for higher-level math courses.
Fractions show parts of a whole. The top number (numerator) tells how many parts you have, and the bottom number (denominator) tells how many parts make a whole.
Decimals are another way to show parts of a whole, especially when dividing by 10, 100, etc. For example, \( 0.5 \) means "five tenths," which is the same as \( \frac{5}{10} \).
Fractions and decimals are just two ways to describe the same thing. You can switch between them by dividing.
Fractions and decimals help us measure things that aren't whole, like pieces of pizza or parts of a dollar.
Pie charts use fractions and decimals to show how much of each slice you get!
A pizza is cut into 8 slices. If you eat 3, you ate \( \frac{3}{8} \) of the pizza.
You have $2.75, which is two whole dollars and seventy-five cents.
Fractions and decimals are ways to represent parts of a whole and are used in measuring, money, and much more.
