each square in the model shown represents 1 whole. what number does the model represent? write the number in decimal form.
Answer
Explanation:
Step1: Count whole - squares
There are 2 whole - squares, which contribute 2 to the number.
Step2: Count parts of a square
The third square is divided into 10 equal parts and 9 parts are shaded. Each part represents 0.1, so 9 parts represent $9\times0.1 = 0.9$.
Step3: Calculate the total number
Add the value of whole - squares and the value of the part of the square: $2+0.9 = 2.9$.
Answer:
2.9
