What is greater 1sixth or 1 eighth?

Answer 1

The greater the denominator the smaller its value. Since eight is greater than six the value of 1eighth is lesser than 1 sixth.

Another way of saying,

1 eighth is nothing but dividing 1 into eight equal parts and 1 sixth is dividing into six equal parts. Obviously the 1 sixth part will be greater than one eighth. For eg. if you share a cake equally with eight friends, the slice be will smaller than when you share equally with six friends.
