The sixth grade class sold magazines for the school fundraiser. Mark, Ellen, Patty, and Rajel compared how many magazines they each sold. Mark sold nine magazines.
For every magazine Mark sold, Ellen sold three magazines. How many magazines did Ellen sell?
For every three magazines Mark sold, Patty sold four magazines. How many magazines did Patty sell?
The ratio of the number of magazines Mark sold to the number of magazines Rajel sold is 3:8. How many magazines did Rajel sell?
Ellen sold 9 x 3 = 27 magazines.
Since Mark sold 9 magazines for every 3 magazines Patty sold, Patty sold 9 / 3 x 4 = 12 magazines.
The total ratio of magazines sold by Mark and Rajel is 3 + 8 = 11 parts.
Since Mark sold 9 magazines, the one part of the ratio represents 9 / 3 = 3 magazines.
Therefore, Rajel sold 8 x 3 = 24 magazines.
