Every formula that divides one changing quantity by another is an algebraic fraction: speed as (distance)/(time), a profit margin as (revenue-cost)/(revenue), or the combined resistance of two components in an electric circuit. Learn to simplify, add, and combine these fractions now and the messy expressions you will meet in O/L equations, ratios, and A/L science will suddenly become manageable.
