Representing percents
In this section, we calculate the percents of numbers using loadingstrip models. Along with these models, we calculate the percents of numbers using our knowledge from previous sections on adding and subtracting decimal numbers and dividing decimal numbers. For example, to determine 75% of a number, we add the decimal values of 50% and 25% of the number. Also, to determine 50% of a decimal number, we divide that decimal number by 2.
