SQL Query Help

I have 2 queries that I would like to join together based on date and a domain field. However, sometimes a date will apear in one table, but not the other. If there is a date in either result I want the row to still show up. It is better explained with the actual queries.

The first query:
SELECT trunc(date_created) day, domain, count(offer_id) requests FROM offer_tracking GROUP BY trunc(date_created), domain  

First Query Example Result:

DAY       DOMAIN                             REQUESTS


--------- -------------------------------- ----------

03-JUL-01 SHAUNM                                    2
03-JUL-01 TEST                                      4
05-JUL-01 SHAUNM                                    1
05-JUL-01 TEST                                      2
11-JUL-01 TEST                                      1
13-JUL-01 TEST                                      2
19-JUL-01 TEST                                      8
20-JUL-01 TEST                                      6

The second Query:
SELECT trunc(date_created) day, domain, count(offer_id) redeems FROM offer_redeem GROUP BY trunc(date_created), domain

Second Query Example Result:

DAY       DOMAIN                              REDEEMS


--------- -------------------------------- ----------

03-JUL-01 TEST                                      2
09-JUL-01 TEST                                      1
19-JUL-01 TEST                                      2
20-JUL-01 TEST                                      1

Desired Combined Result:
DAY       DOMAIN                             REQUESTS    REDEEMS RATIO


--------- -------------------------------- ---------- ---------- -----


03-JUL-01 SHAUNM                                    2          0     0
03-JUL-01 TEST                                      4          2   0.5
05-JUL-01 SHAUNM                                    1          0     0
05-JUL-01 TEST                                      1          0     0
