Question

what decimal number is represented by the model?

Explanation:

Step1: Count total squares

The grid has 100 small - squares (10 rows and 10 columns), representing 1 whole.

Step2: Count shaded squares

There are 7 shaded squares.

Step3: Calculate decimal value

Since each small - square represents $\frac{1}{100}=0.01$, 7 shaded squares represent $7\times0.01 = 0.07$.

Answer:

0.07
