a student finshed 8 of her quiz problems in class. if the ratio of problem she finished to problems she still had left was 4:1 how many home work problems did she have total
I can't really explain this well but, when you double 4 you get 8 (which is how many she did), so since you doubled 4 you also have to double 1 which would be 2. Then add 8 and 2 and you get 10
