Ill give u brainliest pls !

my sentence is = "la chicas están hablando"

my spanish teacher said i have to use the present tense word of "hablando"

how do i do

Well when your teacher says to use the present tense of the word hablando.

The reason is because you wrote the past tense in the Yo form verb.

Hablando means talking in the past tense which was what you used.

the Correct  word you should use is hablar which means (to speak).

Your sentence should be:

La chicas están hablar

Hopes this helps.
