Beware not to mix up fractions (to describe a part of a whole: half, third, fourth...) and ordinal numbers (to describe an order/rank: 1st, 2nd, 3rd, 4th, ...).
For ordinal numbers, see Forming ordinal numbers (1st, 2nd, 10th...).
Look at these examples of fractions:
To express fractions in French, you usually use both cardinal (un/deux/trois...) and ordinal numbers (premier/cinquième...) the same way as in English (one fifth).
Note also that just like in English, the second number is plural if the first is.
ATTENTION:
Here are the irregular fractional numbers:

Joakim asked : why one says "tiers monde" rather than "troisième monde" ?

Bonjour Joakim !
The expression "le Tiers Monde" to say "the Third World" is fixed as it is in English: this is the only way to say this in French.
"Le Troisième Monde" would feel like there are more than one world, i.e. one planet, when here it's more of a division of the world into three "parts", hence the use of the fraction here.
À bientôt !

Trois sixièmes ou un demi
I appreciate that exercise is showing how to write fractions. However, do they actually say "trois sixièmes" instead of "un demi" in everyday life?

Hi William,
I cannot think of a situation in every day life when you would use 'trois sixièmes' except in a Maths lesson...
