    Study Notes

    Solving Multi-Step Word Problems Involving Fractions and Decimals

    Real World Applications

    • Cooking and recipes: fractions and decimals are used to measure ingredients and scale recipes up or down.
    • Shopping and discounts: understanding fractions and decimals helps calculate discounts, sales tax, and change.
    • Measurement and conversion: fractions and decimals are used to convert between units of measurement (e.g., inches to feet).
    • Science and engineering: fractions and decimals are used to represent proportions and ratios in scientific and engineering applications.

    Word Problem Strategies

    • Read and Understand: read the problem carefully, identify the key elements, and understand what is being asked.
    • Identify the Operation: determine the operation(s) needed to solve the problem (e.g., addition, subtraction, multiplication, division).
    • Represent the Problem: use visual representations (e.g., diagrams, charts) or equations to represent the problem.
    • Solve the Problem: use the identified operation(s) and representation to solve the problem.
    • Check the Answer: check the answer for reasonableness and accuracy.
    • Use Visual Models: use visual models (e.g., number lines, fraction strips) to represent fractions and decimals and solve the problem.
    • Work Backwards: work backwards from the solution to check if the answer is correct.
    • Break Down the Problem: break down the problem into smaller, more manageable parts, and solve each part separately.
