Total students = 870 +800 = 1670

 

 

2/3  * 870 = boys spanish = 580

2/5  * 800 = girls                 = 320     total 900 who study spanish out of  1670 total students

                                                                   1670 - 900 = 770 out of 1670 who do not study spanish    770/1670 = 77/167
