Query help, Percentages / ratio to reports / nests

Question

Hi
I have a query that returns data like this
D_NO POINTS COUNT_POINTS ID_COUNT
4002 L_T_69 12 282
4219 L_T_69 1 151
4228 L_T_69 18 193
4229 L_T_69 7 181
4230 L_T_69 0 197
I need to also output a column that works out a percentage of count_points and Id_count. e.g 12/282 * 100 = 4.2
I had a try with ratio to reports function but no joy for me. I think i need to add in
another nested select or something but what i was trying wasnt working.
Can anyone help.
here is the query so far
SELECT D_NO,
GROUPS.POINTS,
DECODE(GROUPS.POINTS, 'L_T_69' , L_T_69) AS COUNT_POINTS,
ID_COUNT
FROM
     (SELECT D_NO,
     Count (CASE WHEN VERBAL <= 69 THEN 1
          END) AS L_T_69,
     COUNT(ID_NUMBER) AS ID_COUNT
     FROM TBL_1
     WHERE VERBAL IS NOT NULL
     group by D_NO)
TBL_1,
( SELECT 'L_T_69' POINTS FROM DUAL )GROUPS
thank you

Not sure if this is what you're looking for but it may give you some clues:
select object_type
      ,has_a_c
      ,type_total
      ,round(100 * (has_a_c / type_total),2) ratio
from
   select object_type
         ,sum (case when instr(object_name,'C') <> 0 then 1
                    else 0
               end) has_a_c
         ,count(*) type_total
   from   all_objects
   group by object_type
OBJECT_TYPE          HAS_A_C   TYPE_TOTAL   RATIO
