Question

what number does the model represent? choose all the correct answers. 2.4 2.04 2.40 24 0.24

Explanation:

Step1: Count whole squares

There are 2 fully shaded squares, so 2.

Step2: Count shaded parts in grid

The third figure is a 10x10 grid (100 parts). 40 parts are shaded: $\frac{40}{100}=0.4$.

Step3: Sum whole and decimal parts

$2 + 0.4 = 2.4$. 2.40 is equivalent to 2.4.

Step4: Eliminate incorrect options

2.04 (0.04≠0.4), 24 (too large), 0.24 (too small) are wrong.

Answer:

2.4, 2.40
