Number of homework problems solved by the student in class = 72 Ratio of the problems she finished to the problems still left = 8:1 Let us assume the common ratio to be = x Then 8x = 72 x = 72/8    = 9 Then The number of problems she still needs to complete = 1 * 9                                                                                      = 9 Then The total number of homework problems she had in total = 72 + 9                                                                                              = 81 So she had a total of 81 homework problems to complete. I hope the procedure is clear enough for you to understand.
