sixth

‘Sixth’ has two meanings:

(1) It can mean one part of six, which is recorded as a fraction, \frac{1}{6}.

For example, the picture opposite shows a cake which has been divided into six equal pieces.

Seren takes one piece of the cake, therefore she has \frac{1}{6}.

(2) It can also mean the number 6 in a sequence of numbers.

It appears after the 5th, but before the 7th.

For example, 7 people are waiting to see the dentist. They have been listed according to the time of their appointment.

Dylan is the 6th person on the list.
