rewrite this query to make sure pick the TIE values

1. select Geo_QName, MAX(cast(ACS18_5yr_B15003025 as decimal)/ACS18_5yr_B15003001) as proportion from b15003 group by Geo_QName order by proportion desc limit 1 ;

I do not need to use limit 1 , I want have TIE values if there will be one

2. SELECT Geo_STUSAB AS myState,

SUM(ACS18_5yr_B15003002)::NUMERIC/SUM(ACS18_5yr_B15003001)AS mySum

FROM b15003

GROUP BY Geo_STUSAB

ORDER BY mySum DESC

LIMIT 1;

do same for this query , no limit, just show MAX values if there is TIE or not
