At 7:00 p.m., there are 1,000 home-team fans and 700 away-team fans at a football game. After 7:00 p.m, 15 home team fans arrive every ten minutes and 5 away team fans leave every ten minutes. What is the ratio of home-team fans to away-team fans at 8:00 p.m. (in fraction form)?

From 7 to 8  there are  6 10-minute periods....so,,,,,

 

At  8PM...there are...1000  + 6(15)   = 1000 + 90  = 1090  home fans

 

At 8 PM  there  are   700 - 6(5)      =  700  - 30  =  670  away fans

 

Home  /  Away    =     1090  /  670   =   109  /  67
