Question

each square in the model shown represents 1 whole. what number does the model represent? write the number in decimal form.

Explanation:

Step1: Analyze the first square

The first square is completely blue, so it represents \(1\) whole.

Step2: Analyze the second square

The second square is divided into \(10\) equal parts (since there are 10 vertical strips), and \(3\) of them are blue. So the fraction of the second square that is blue is \(\frac{3}{10}\), which is equal to \(0.3\) in decimal form.

Step3: Combine the two parts

To find the total number represented by the model, we add the value of the first square and the value of the blue part of the second square. That is \(1 + 0.3 = 1.3\).

Answer:

\(1.3\)
