Question

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

Explanation:

Step1: Count full squares

There are 2 fully blue squares, each representing 1, so \( 2\times1 = 2 \).

Step2: Analyze the third square

The third square is divided into 10 equal parts. 9 parts are blue. So the fraction of the third square that's blue is \( \frac{9}{10} = 0.9 \).

Step3: Sum the values

Add the value from the full squares and the third square: \( 2 + 0.9 = 2.9 \).

Answer:

\( 2.9 \)
