Hot Stuff!!!!

 

If you are in Georgia, it should be easy to find the fraction and decimal that says, "I am hot."

Each of the letters represents a different digit from 0-9. Find the fraction.

 

 

I began this search the easiest way possible...I only had 9 numbers to work with, so why not begin just sticking in digits in some sort of systematic fashion. For example, I = 1, A = 2, M = 0. After keeping my numerator as 1 and constantly changing the numbers in my denominator consecutively, I found that 1/27 = .037037037. I continued...and found 1/37 = .027027027. I figured immediately that I must be on to something, but just to prove to myself, I went through all the twos, i.e. 2/10, 2/21, 2/22...2/27...2/37. Again, I saw the same type of repetition in decimals. The fractions 2/27 = .074074074 and 2/37 = .054054054...oh goodness...this one actually works. I wondered if another fraction would work and still fit in the same criteria. I continued...3/27 = well, to say the least it was a repeating decimal however, it did not work, but 3/37 = .081081081 did work although it did not fit my "different digits" criteria. Okay, let's go to the fours. The fraction 4/27 = .148148148 and 4/37 = .108108108...wow, this one works too!!! So now I am assuming it works with multiples of 2...NOT!!! The fractions 6/27 = .22222 and 6/37 = .162162162 did not work they did not fit the criteria. Now, I figured maybe, just maybe it worked by finding the powers of 2 in the numerator and having 37 as the denominator...let's see...8/37 = .216216216. Hot dog! It did work!!!

 

So my answers to are 2/37, 4/37 and 8/37.

 

 

 

I guess...I AM HOTHOTHOT!!!
