All you do is multiply the left column to get the right column or to divide the right column to get the left column.
So you want to go from left to right in the first row. 6*4 = 24 Second Row is complete. Third row is Right to left so you would divide by 4 which will give 12 Fourth row multiply by 4 ; 4 * 15 = 60
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
