Referring to “vous adorerez cette autre idée : modifier un pyjama en flannelle défraîchi.”

for

“you will love this other idea: making alterations to a pair of faded flannel pyjamas.”

I can only find “flanelle” (one “n”, not two) in the dictionaries. And this is a female noun. So should these answers all be “…en flanelle défraîchie.”?

This lesson needs some real sentences to demonstrate how to use the expressions.

Example "Add a liter and a half of water" = Ajouter un LITRE et demi d’eau" but "Add a liter and a third  of water" == "Ajouter un litre et UN tiers d'eau".  Sentences along these lines. I apologize if there is another lesson showing this. If there is it should be linked.  Note also I am confused by the inconsistency of online translators with the above examples..

Additional difficult sentences " One third of  students had a passing grade" == "Un tiers des étudiants ont obtenu une note de passage" OR " Un tiers des étudiants A obtenu une note de passage"??? I have seen both.
