Answer:
Nosotros estamos leyendo.
Step-by-step explanation:
For present progressive, you start with the appropriate estar conjugation. The estar conjugation for nosotros is estamos so we use estamos. Lastly, second verbs do not change according to pronoun in the present progressive. You remove the ar, er, or ir ending and change it to ando or iendo (ar -> ando and er, ir -> iendo). Leer is irregular, so instead of leendo, it is leyendo.
Examples:
Mirar = Mirando
Tener = Teniendo
Escribir = Escribiendo
I'm a bit late, but good luck!
