A fraction a/b means a parts out of b equal parts. Fraction-of questions multiply; comparison questions need a common base.

💡 Quick tricks

a/b of N = N × a ÷ b: divide first if b divides N exactly.
To compare fractions, cross-multiply or turn them into decimals.
a/b > c/d exactly when a × d > b × c (with positive denominators).
