How to Find Rate Using Fractions

The video tutorial explains how to solve a standardized math test question involving the calculation of a rate using fractions. The problem involves determining the rate at which Brayden adds flour to a mixture, given as 1/3 cup every 1/2 minute. The tutorial breaks down the problem by explaining the concept of rate as a ratio, setting up the problem as a complex fraction, and solving it by multiplying by the reciprocal. The final answer is calculated as 2/3 cup of flour per minute.
