How to solve it (Cross-multiply to compare): Compare a/b and c/d: work out a × d and c × b — the bigger product goes with the bigger fraction. Add: make the bottoms the same (use the LCM), add the tops, then simplify. Fraction of a number: divide by the bottom, multiply by the top (3/4 of 48 = 48 ÷ 4 × 3 = 36).
