Homework for Monday, Sept. 28: Create your own Babylonian-style base 60 multiplication table for the number forty-five

       I  spent some time to solve this mystery. It is interesting. Based on my results, I concluded this is a reciprocal convert to a decimal table. There did not have 7,11, and 13 since the numbers 7, 11, and 13 are all prime numbers their reciprocal cannot change to corresponding decimals. 

     

 

        It was fun to find the pairs to multiply to 45. I was trying to get two fraction numbers that time to 45, I found it was a bit harder to find both fractions in the pair.
