How would I add to my SQL Query to add a Percentage Column in my Report?

SELECT DISTINCT T2_1.LITERAL_NAME,
       T1.REFERENCE_ID,
       T1.NAME AS URL1_title,
       T1.URL AS URL1,
       T1.ACTUAL_WORK,
       T1.PLANNED_WORK
FROM RIDW.VW_REQUEST T1
LEFT OUTER JOIN RICALM.VW_RQST_STRING_M_EXT T2
ON T2.REQUEST_ID=T1.REQUEST_ID AND T2.NAME='complexity'
  LEFT OUTER JOIN RICALM.REQUEST_ATTRDEF T2_2
  ON T2_2.REQUEST_TYPE_ID=T1.REQUEST_TYPE_ID AND T2_2.NAME=T2.NAME
    LEFT OUTER JOIN RICALM.VW_RQST_ENUMERATION T2_1
    ON T2.VAL LIKE CONCAT(CONCAT('%|',T2_1.EXTERNAL_ID), '|%') AND T2_1.PROJECT_ID=T1.PROJECT_ID AND T2_1.ENUMERATION_NAME=T2_2.DATATYPE
WHERE T1.PROJECT_ID = 52  AND
(  T1.REQUEST_TYPE = 'CLM Migration Inventory'
) AND
(T1.ISSOFTDELETED = 0) AND
(T1.REQUEST_ID <> -1 AND T1.REQUEST_ID IS NOT NULL) ORDER BY T2_1.LITERAL_NAME asc
