In a poll in a school, students picked whether they liked apples or oranges more. The ratio for this was
5:8. Five absent students were polled the next day and each of them preferred apples and the new ratio was 5:6. How many people were originally polled?

Best ResponseYou've already chosen the best response.0it might be easier to look at it in fraction form y/(xy) = 5/8 (y+5)/(xy) = 5/6 y is the students who like apples, x is the total num of students xy students like oranges you have to solve the system of proportions for x and y
