pdf Ratio and Proportion Story Problems - B

This Ratio and Proportion Story Problems – B worksheet provides structured, real-world practice solving proportional reasoning problems across a variety of contexts. Students must interpret each scenario, identify the proportional relationship, and determine the unknown value using multiplicative reasoning.

Problems include determining the number of apples given a 3 to 5 ratio and a total of 40 fruits, finding how many students did not pass based on a 4 to 1 pass-to-fail ratio, extending test performance from \(\frac{27}{30}\) to a 50-question test, and calculating non-rotten tomatoes when \(\frac{4}{20}\) are rotten. Additional scenarios involve simplifying ratios such as 20 boys to 12 girls, comparing dimes to pennies, solving a scale drawing problem using proportional side lengths, and expressing large ratios such as 950 students to 50 teachers in lowest terms.

Because students must read carefully, set up proportions, and simplify results, this resource strengthens both conceptual understanding and procedural fluency. The emphasis on showing work reinforces structured problem-solving habits while highlighting that proportional reasoning appears in percent, scale, and real-world rate situations.
