"She runs in a field."

Translation: Ela corre em um campo.

[Zaratexas]

DL hasn't taught "num" before now! Sucks that I got it wrong .

[mikocot]

and why is it em um or num instead of no?

[Paulenrique]

no = in the / num = in a

[KTKee-EnglishEng]

Is num used in contemporary Portugese?

[Paulenrique]

Indeed, all the time!! Not the same for dum (de+um) and duma (de+uma).

[markhachey]

Why is there a 1 in answer?

[Jerry625941]

even though you asked this question 2 years ago, duolingo will sometimes correct "the" to "a" by saying you only need (1) in your answer

[Rijk169768]

i translated it as ''num campo" The owl says it's correct but writes "em um campo" Which of the 2 would be Portuguese portuguese?

[mc_maky]

Duo translates it as 'em um campo' instead of num campo. I always thought using construction em + um/uma is incorrect and it should be always num or numa, isnt it?

[Paulenrique]

Some contractions are not mandatory. You can use "em um/uma".
