This Grade 5 worksheet applies ratios to real engineering, cooking, and mapping situations. Students compute scale-model dimensions, mix ingredients in three-part ratios, and convert map distances to real-world miles. Both multiple choice and fill-in problems require multiple steps, including dividing total parts and multiplying by individual ratio components. The challenges prepare fifth-graders for proportional reasoning in middle school while connecting math to everyday experiences like building, cooking, and travel.

Part B: Fill in the Blank
Write the correct answer on each line.
1. Smoothie uses banana, berry, and yogurt in 3:2:5. For 20 oz total, banana is 6 oz.
2. A scale model uses 1:36. A real bus 540 inches long is modeled at 15 inches.
