Question

I need these in a sentence

Answer 1

Well hacer means to do, to make and duerme means to sleep, suelen is the present form of soler in the third person plural to use to and ejercicio means to exercise and en means in or on and una means one and silla means chair so it is easier to make a sentance out of it if it is like this 
hacer= to do, to make
duerme= to sleep
suelen=to use
ejercicio=to exercise
en=on or in
una=one
silla=chair
so you have to decifer it and find all the possible words for a sentance

hope you find this usefull.

Answer 2

Suelen Hacer ejercicio en una silla
