Lottie and Adele sent us a great solution to this problem. They answer each part in turn and explain clearly as they go along:1. To make it balance with 10 on one side, using only one hook, you can put two on the 5 or one on the 10 or five on number 2 or ten on 1.
Thank you to you both. I wonder if there are other ways of making the equaliser balance if you have one weight on the 10 hook on one side and can use the 3 hook and one other hook on the other side? Don't forget that you can have more than one weight on a hook.
