The answer is 35 7/8. We know that to get the mean, you must add up all the numbers and divide by the amount of numbers. Set up the equation (36 3/4 +36 3/8+37 1/2+n)/4 = 36 5/8. After you solve for n, the missing number, you should get 35 7/8.
I would say between 2 and 4 because you are using ration recipe 4: 8 :4 10:5 12:6 recipe 2: 6:3 10:5 14:7 all you doing is trying to find whats ratio is greater.. hope it helps
