The video tutorial covers comparing and ordering rational numbers, including fractions and decimals. It introduces formal methods like finding the least common multiple and equivalent fractions, as well as shortcut methods like cross-multiplication. The tutorial also addresses comparing decimals, especially those with repeating patterns, and ordering rational numbers, including negative values. It concludes with advanced examples and emphasizes using calculators for mixed fractions and decimals.

What is the first step in the formal method of comparing rational numbers?

• Use a number line

• Convert fractions to decimals

• Cross-multiply the fractions

• Find the least common multiple of the denominators
