Direct-object pronouns

Question

I am trying to finish up my Spanish homework but I am stuck on a worksheet page. The directions are "Your parents are asking you the following questions. Answer them in two different ways. First, answer each question by placing the direct-object pronoun before the verb; second, answer each question by placing the direct-object pronoun at the end of the infinitive or present participle."

I am not quite sure how to do this. I am terrible at Spanish and I don't know what words to use or where to put them.

The example is:
¿Está leyendo el periódico?

Sí, (No, no) lo estoy leyendo.

Sí, (No, no) estoy leyéndolo.

And the first two sentences I have to do are:

¿Tienes que escribir una carta?

¿Estás haciendo las tareas en la computadora?

Thank you very much to anybody that can help me!
