1. Problem Description

The problem asks us to identify which strip model represents 70%. Each strip is divided into 10 equal parts.

2. Solution Steps

First, we need to determine the value of each individual part in the strip.
Since the strip is divided into 10 parts, each part represents 1/101/10 or 10% of the whole.
Next, we analyze each model:
Model 1 (Green): 7 parts are shaded. Therefore, the percentage represented is 7∗10%=70%7 * 10\% = 70\%.
Model 2 (Yellow): 4 parts are shaded. Therefore, the percentage represented is 4∗10%=40%4 * 10\% = 40\%.
Model 3 (Orange): 3 parts are shaded. Therefore, the percentage represented is 3∗10%=30%3 * 10\% = 30\%.
Since we are looking for the model that represents 70%, the correct model is the first one (Green).

3. Final Answer

The first model (Green) shows 70%.
