Try starting off by putting weights on the 1 hook. How many will
you need to balance with 10?
What about trying the 2 hook? How many will you need this
time?
Can you keep going in this way?
If I had two weights on the 10 hook, what would this be the
same as in total?
If I then hang two weights on the other side, what would that
balance with? So how many will I need on the 2 hook to balance
with the two on the 10?
