This animation shows three ropes of different lengths—425 cm, 52.8 dm, and 4.6 m—being converted to the same unit and joined into one rope. It highlights how each knot shortens the total length by 0.9 dm, with two joints removing four rope ends. Step-by-step addition and subtraction reveal the final rope length, helping students practice unit conversion and multi-step word problems in a visual, engaging way.

Create a colorful educational mathematics infographic for Grade 5 elementary school students titled **“How Long Is the Rope After Being Joined?”** **DESIGN STYLE** Use a cute cartoon illustration style with pastel green, cream, and orange colors. Create a vertical infographic poster with clear English text, large readable fonts, colorful rope illustrations, arrows, knots, and numbered steps. IMPORTANT: Include actual visual illustrations of the ropes. Do not create a text-only infographic. **1. SITUATION** Sinta has three pieces of rope: - Rope A = 425 cm - Rope B = 52.8 dm - Rope C = 4.6 m The three ropes are joined together to make one long rope. Each connected rope end is shortened by 0.9 dm. **2. VISUALIZATION OF THE ROPES** Draw three separate cartoon ropes: - Rope A: pink, labeled “425 cm” - Rope B: blue, labeled “52.8 dm” - Rope C: yellow, labeled “4.6 m” Below them, draw the three ropes connected in one straight horizontal line, with exactly two visible knots: - Joint 1 connects Rope A and Rope B. - Joint 2 connects Rope B and Rope C. **CRITICAL VISUAL DETAIL:** Each joint connects TWO rope ends. There are TWO joints and FOUR connected rope ends in total. Clearly mark all four ends with arrows and labels: - Rope A end at Joint 1: −0.9 dm - Rope B end at Joint 1: −0.9 dm - Rope B end at Joint 2: −0.9 dm - Rope C end at Joint 2: −0.9 dm Show the four shortened ends clearly in the illustration. Do not show only two reductions. **3. STEP-BY-STEP CALCULATION** Step 1: Convert all rope lengths to meters. - 425 cm = 4.25 m - 52.8 dm = 5.28 m - 4.6 m = 4.60 m Step 2: Calculate the total length before joining. 4.25 m + 5.28 m + 4.60 m = 14.13 m Step 3: Calculate the total reduction. There are four connected rope ends, and each end is shortened by 0.9 dm. 4 × 0.9 dm = 3.6 dm 3.6 dm = 0.36 m Step 4: Calculate the final length. 14.13 m − 0.36 m = 13.77 m **4. CONCLUSION** Display the answer in a large, colorful highlighted box: “The final length of Sinta’s rope is 13.77 meters.” **FINAL REQUIREMENTS** - Use English for all text. - Include actual cartoon illustrations of all three ropes. - Show exactly two knots and four shortened rope ends. - Place a −0.9 dm label next to each of the four connected ends. - Use arrows to explain the joining process. - Make the mathematical calculations accurate. - Keep the layout neat, colorful, and suitable for Grade 5 students.
