Question

Out of 70 identical show pieces, 49 are broken. Find the fraction of
i) the total number of show pieces and the show pieces broken​

Answer 1

Theorem. Every positive integer can be uniquely expressed in the form

a0+(3⋅a1)+(32⋅a2)+⋯+(3n⋅an)a0+(3⋅a1)+(32⋅a2)+⋯+(3n⋅an), … (⋆⋆)

where each ak∈{0,1,2}ak∈{0,1,2}.

Application. Consider weights from the sequence 11, 33, 3232, 3333, …… . To weigh an object of weight NN kg., express NN in base 33, as in eqn. (⋆⋆). Place the object to be weighed on the left scale. Place the weight 3k3k on the right scale if the corresponding coefficient akak equals 11, weights 3k+13k+1 on the right scale and 3k3k on the left scale if akak equals 22, and don’t place the weight 3k3k on either scale if akak equals 00.
