a server to cook ratio of 5 to 2. the total number of cooks and servers are 42 how many servers does stand steakhouse employ.

If you divide 42 into groups of 7 then that means that each group would have 5 servers and 2 cooks. so the steps are, you divide 42 by 7 and get 6 (there are 6 groups of 7) so 6*5 would be the number of servers and 6*2 would be the number of cooks. #server = 30 #cooks=12
