Identifying Proportional Relationships 7.RP.A.2 | Math Defined with Mrs. C.

🔢 **Are These Ratios Proportional? Let’s Find Out!** 🔢 Welcome back to Math Defined! I’m Mrs. C, and today we’re unlocking the mystery of proportional relationships! What does it mean for two ratios to be proportional? And how can we check? 🤔 In this video, I’ll show you **two easy methods** to determine whether two ratios (or even a whole table of values) are proportional: ✅ **Simplifying Ratios** – Reduce each ratio and compare! ✅ **Cross Products Property** – Multiply across and check if the products are equal! We’ll go through multiple **step-by-step examples**, including: ➗ Checking if **1:3 and 7:21** are proportional ✖️ Using **cross products** to compare **1/2 : 3 and 3/2 : 9** 📊 Analyzing **ratio tables** to determine proportionality 🧠 A final **challenge** to test your skills! 💡 **Which method do you prefer?** Let me know in the comments! 📌 **Timestamps:** 0:00 Introduction 0:18 What Does Proportional Mean? 0:41 Method 1 – Simplifying Ratios 1:20 Method 2 – Cross Products Property 2:00 Checking Proportionality in Tables 6:41 Final Challenge 7:47 Wrap-Up 🎉 **Like, Subscribe, and Keep Math Awesome!** 🎉
