Question

Fill in the blank with the singular form of las mochilas:

Answer 1

For this case we have the following sentence:

Las mochilas.

This sentence is written in the plural.

That is, it means that we have more than one object.

We must transform the sentence into singular, that is, a single object. For this, we must eliminate the letter "s" of both words.

We have then:

La mochila

Answer:

the singular form of las mochilas is:

La mochila

Answer 2

Just remove the "s" and you have your answer.
"La mochila"
