0.3
0.33
0.67
0.7

Answer 1

To determine the decimal that represents the portion of the model that is shaded, you can use the formula:

\[ \text{Decimal} = \frac{\text{Number of shaded cubes}}{\text{Total number of cubes}} \]

In this case, there are 30 shaded cubes out of a total of 100 cubes:

\[ \text{Decimal} = \frac{30}{100} = 0.3 \]

Therefore, the correct answer is:

0.3
