Convert Grid Squares to Fraction: Identify 7/7 from Visual Model

The problem involves finding the fraction represented by shaded parts in a drawing. Here's a step-by-step guide to solve it:

• Step 1: Count the total number of sections in the drawing. There are 7 blocks arranged linearly.
• Step 2: Since each block appears to be fully shaded, count those shaded. Each of the 7 blocks is shaded.
• Step 3: The fraction is formed by placing the number of shaded sections over the total sections. Thus, the fraction is $\frac{7}{7}$.

The fraction for the shaded portion of the drawing is $\frac{7}{7}$, which is a complete whole, as every block is shaded.

Therefore, the solution to the problem is $\frac{7}{7}$.
