union

I have the following query, in the top select statement (sum(l.app_ln_amnt)/count(l.app_ln_amnt)) works well but in the union I want to find the total of (sum(l.app_ln_amnt)/count(l.app_ln_amnt)) query from the top select statement However my solution seems to be off I need some help please

select 
(sum(l.app_ln_amnt)/count(l.app_ln_amnt)),


from receipt_history l

     UNION

select 
SUM(sum(l.app_ln_amnt)/count(l.app_ln_amnt)),


from receipt_history l
