Answer:
The percent that represents the model is 63%
Explanation:
The model is 100 squares, correct? Well, there are 63 shaded. We can easily put that into a percent because percents are always out of 100. In other words, if there was X/100, the X would be the percent. In this case, 63 is in the X spot because that is how many there are shaded, which makes the percent 63%.
