Question: A science educator designs a learning module where students collect data using sensors. The number of successful data readings from two sensors in a lab session are in the ratio $5:8$. If the total number of readings is 143, how many readings were from the sensor with the smaller count?

["Unlocking STEM Learning: How Sensor Data Ratios Help Students Grasp Real-World Science", "In today’s education landscape, hands-on learning powered by technology is reshaping how students engage with science. One emerging method involves equipping lab sessions with digital sensors that collect accurate, real-time data. When students analyze sensor outputs, practical math challenges help solidify both analytical and scientific thinking. \nRecently, a classroom activity captured attention when students collected readings from two sensors, revealing a ratio of 5:8—17 total readings with a hidden but precise total of 143. This beginner-friendly problem offers more than a math exercise—it reveals how ratio analysis supports scientific reasoning in modern STEM classrooms.", "---", "### Why This STEM Challenge Is Gaining Traction", "The use of sensor-based data collection in education reflects a growing trend toward experiential learning in U.S. classrooms. As students transition from theory to applied science, tools like sensor technology allow them to conduct experiments with greater precision. The ratio question—ROI-driven by data literacy trends—stands out in digital content because it aligns with today’s focus on measurable, hands-on learning. Due to rising demand for interactive STEM curricula, educators are innovating with tools that blend math, science, and real-world application. When students interpret these sensor outcomes, they not only practice algebra but also develop critical thinking skills essential for future STEM careers.", "---", "### How the Ratio Works in This Lab Exercise", "The problem describes two sensors whose successful readings are in the ratio 5:8, making a total of 143 sensor outputs. While many associate such ratios with physical experiments, the real value lies in the process: understanding proportions and applying basic math to interpret real data.", "Let the number of readings from the smaller sensor be $5x$ and the larger sensor $8x$, so the total reads are: \n$$ 5x + 8x = 13x = 143 $$ \nSolving for $x$ gives: \n$$ x = 143 \div 13 = 11 $$", "Thus, the sensor with the smaller count recorded: \n$$ 5x = 5 \ imes 11 = 55 $$", "This step-by-step breakdown builds clarity, encouraging readers to follow logical reasoning—essential for successful data interpretation and reinforcing problem-solving confidence.", "---", "### Common Queries About the Data Ratio Puzzle", "Many students and educators ask: How do ratios translate into real lab results? This problem exemplifies how proportional thinking supports accurate data analysis. Another common question is the precise method for"]
