5/86 = k Mod8 (I made it up, that's probably why it doesn't work) (k is in the set 0,1,2,3,4,5,6,7 (since it is mod 8))
This is my working
5=86k mod 8
so 6k must equal one of the following 5,13,21,29,37,45,53,61,69,77
but none of these numbers are exactly divisible by 6.
Does this mean that there is no solution, or have i done something wrong?
Thanks I like Serena,
I never did any modulus arithmetic when I was younger. It is all completely new to me.
I really don't think I understand the concepts much at all.
I was told elsewhere that modulus arithemetic only used whole numbers and now you are introducing fractions.
I'll think about what you have told me, but I really don't get it.
Don't be too concerned, it is not important, I am only trying to fluff my knowledge out at the edges. Like the tassles on a mat.
If it is too difficult I lose interest very easily.
