Step-by-step explanation: 
For Mr Rowley,
Ratio of Number of home works to the number of exit tickets = 
                                                                                                       = 
                                                                                                       = 6:7 
For Ms Rivera,
Ratio of Number of home works to the number of exit tickets = 
                                                                                                       = 
                                                                                                       = 6:7 
Since, both the ratios are same, fractions will be proportional.

Depending on how many paintings there were you would divide that number by 129 to figure out how long it took to complete one painting. Hope this helps.
