The problem asks us to identify which of the given models represents 60%. Each model consists of a bar divided into 10 equal parts, where some parts are shaded. We need to find the model where the number of shaded parts corresponds to 60% of the total parts.

1. Problem Description

The problem asks us to identify which of the given models represents 60%. Each model consists of a bar divided into 10 equal parts, where some parts are shaded. We need to find the model where the number of shaded parts corresponds to 60% of the total parts.

2. Solution Steps

First, we need to determine what 60% of 10 parts is.

$Percentage = (Part / Whole) * 100$

We want to find what number corresponds to 60% of

1

0. $Part = (Percentage / 100) * Whole$

$Part = (60 / 100) * 10 = 0.6 * 10 = 6$

So, we are looking for the model with 6 shaded parts.

Now, let's examine each model:

- The first model has 5 shaded parts.

- The second model has 4 shaded parts.

- The third model has 6 shaded parts.

3. Final Answer

The third model shows 60%.
