Format decimal with a Slash

Question

int1     dec1     int2     dec2     result
54     12     49     02     5/10
54     12     40     11     14/1
54     12     30     05     24/07
54     12     26     06     28/06What the query should do is, make a whole number of int1& dec1                    
like for the first row, 54.12 and similarly 49.02 for int2 & dec2                    
the result should be calculated finding the difference in this format                    
54.12-49.02 = 5/10 ( in this format).
i tried with the first row of data above but just not able to get the decimal format correctly.
SELECT substr(to_char((to_number(to_char(55-1,'fm09')||'.'||'12') - to_number(to_char(49,'fm09')||'.'||TO_CHAR(2,'fm09'))),'fm99.99'),1,2)||'/'||
       substr(to_char((to_number(to_char(55-1,'fm09')||'.'||'12') - to_number(to_char(49,'fm09')||'.'||TO_CHAR(2,'fm09'))),'fm99.99'),4,2) FAGE
FROM DUAL;
FAGE
5./
SELECT to_char(floor((to_number(to_char(55-1,'fm09')||'.'||'12') - to_number(to_char(49,'fm09')||'.'||TO_CHAR(2,'fm09')))),'fm99')||'/'||
       to_char(floor((to_number(to_char(55-1,'fm09')||'.'||'12') - to_number(to_char(49,'fm09')||'.'||TO_CHAR(2,'fm09')))),'fm99') FAGE
FROM DUAL;
FAGE
5/5will any one suggest me with the correction please.

How about simply:
SQL > WITH t AS (
  2     SELECT 54 int1, 12 dec1, 49 int2, 02 dec2 FROM dual UNION ALL
  3     SELECT 54, 12, 40, 11 FROM dual UNION ALL
  4     SELECT 54, 12, 30, 05 FROM dual UNION ALL
  5     SELECT 54, 12, 26, 06 FROM dual)
  6  SELECT int1, dec1, int2, dec2,
  7         (int1 - int2) ||'/'||(dec1 - dec2) result
  8  FROM t;
      INT1       DEC1       INT2       DEC2 RESULT
        54         12         49          2 5/10
        54         12         40         11 14/1
        54         12         30          5 24/7
        54         12         26          6 28/6If you really nned the leading zero for the dec result (your expected output has some with and some without) simply add a to_char around the dec subtraction:
SQL > WITH t AS (
  2     SELECT 54 int1, 12 dec1, 49 int2, 02 dec2 FROM dual UNION ALL
  3     SELECT 54, 12, 40, 11 FROM dual UNION ALL
  4     SELECT 54, 12, 30, 05 FROM dual UNION ALL
  5     SELECT 54, 12, 26, 06 FROM dual)
  6  SELECT int1, dec1, int2, dec2,
  7         (int1 - int2) ||'/'||TO_CHAR((dec1 - dec2), 'FM00') result
  8  FROM t;
      INT1       DEC1       INT2       DEC2 RESULT
        54         12         49          2 5/10
        54         12         40         11 14/01
        54         12         30          5 24/07
        54         12         26          6 28/06John
