Key idea: Comparing fractions
**Same denominator (like fractions)**: just compare the numerators. 5/7 > 3/7 because 5 > 3.
**Same numerator**: the bigger denominator means smaller pieces, so smaller value. 1/4 > 1/8 — the same one piece is bigger when the whole is split into fewer pieces.
**Neither same**: rewrite both with a common denominator (a denominator both fractions can share, often the LCM of the two denominators). Then compare numerators.
