Joe, Bob and Aliyah had some candy. Joe had twice as much as Bob. Aliyah had 5 more pieces than Bob. If they had 49 peices of candy all together, use an equation to find out how much candy Joe had. Just put the number in the answer box without the label - put the label on your paper.

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.

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
