Substitute each of the capital letters by a different base ten digit from 0 to 9 to satisfy this set of alphametic
relationships. None of the numbers can contain any leading zero.
) = 64/37, and:
is a prime number.
Ans: 497728/287749 AT=97
It was clear to me that ra/le ratio should be close to 64/37,
thus limiting the range of possiible contenders .
64/37 is close to 63/36=7/4=14/8=21/12 etc
So after few numbers I've reached 49/28 and AT being prime the solution was imminent.
