How to Form Fractions in French Grammar

In French, fractions are formed using cardinal numbers and ordinal numbers. In this lesson, we will explore how to form fractions in French.

Using Cardinal Numbers

To form a fraction using cardinal numbers, you simply place the cardinal number representing the numerator (top number) followed by the word "sur" (meaning "over" or "out of") and then the cardinal number representing the denominator (bottom number). For example:

• 1/2 -> Un sur deux (One out of two)
• 2/3 -> Deux sur trois (Two out of three)

Using Ordinal Numbers

To form a fraction using ordinal numbers, you first use the ordinal number representing the numerator (top number) followed by "demi(e)" (meaning "half"). Then you add the word "partie(s) de" (meaning "part(s) of") followed by the ordinal number representing the denominator (bottom number). For example:

• 1/2 -> Une demi-partie de deuxième (Half a part of second)
• 3/4 -> Trois demi-parties de quatrième (Three and a half parts of fourth)

Note that when the denominator is not a multiple of two, you add the plural ending "-s" to "demi(e)" and "partie(s)". For example:

• 1/3 -> Une demi-partie de troisièmes (Half a part of third)
• 2/5 -> Deux demi-parties de cinquièmes (Two and a half parts of fifth)

Conclusion

Forming fractions in French is a useful skill for everyday conversations and mathematical expressions. By understanding the rules for forming fractions using cardinal and ordinal numbers, you can improve your French language skills and communicate more effectively with native speakers.
