The Total column displays the state's or region's total population. The Number column indicates how many Hispanic (Latino) people live in a certain state or area. The proportion of Hispanic (Latino) individuals in the overall population of the state or area is shown in the percent of Total Population column.
proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.
let's check the answers to see if they are proportional.
question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.
question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.
question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other
question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
