Erro comum:
Learners sometimes think 'fraction' can be used for any 'part', but it usually suggests a relatively small or limited part, often with a sense of measurement. They may also confuse 'fraction' with 'faction' (a group within a larger group), which is unrelated. In the pattern 'a fraction of', the verb can agree with either the fraction (singular) or the following noun; both 'A fraction of the students is absent' and 'A fraction of the students are absent' can occur, but many speakers prefer the plural verb in everyday speech.

They also may forget that, in English teaching, 'fraction' usually refers to a number written with a numerator and denominator, not to any small amount in general (for that, 'a fraction of' is used).
