Alice stumbled on a another question that puzzled her:
times times ... times
She has a clue on a strip of paper which says: LEAVE YOUR ANSWER IN DECIMAL NOTATION
What is the answer then?

Lets 'complexify' the fractions by writing it down using simple operations:
2 1 = 1/2 , 3 2 = 2/3 , 4 3 = 3/4 , ... 9 9 9 8 = 98/99 , 1 0 0 9 9 = 99/100
/ means division and * means multiplication
Our result of 'complexifying' the fractions should be 1/2 2/3 3/4..98/99*99/100
Observe that from the first two fractions it is 1÷2*2÷3 and we notice the 2's get cancelled because they are the same number with an inverse operation. So we get b l a n k 1 times 3 b l a n k and following the same procedure we cancel the 3's , the 4's and so on until we get 1 as the only numerator left and 100 as the only denominator left so we can put the one above the 100 like this 1 0 0 1 which is equivalent to 0.01 and that is the answer.
