Partial Solution to "Most Filipino" Cities Problem

Below is a
partial solution to the challenge to write an SQL query to find to list the US cities that have the highest percentage of Filipinos.

SELECT DISTINCTROW POPDATA.CITYNUM,
COUNT(*)FROM POPDATA
WHERE POPDATA.ANCNUMBER=720
GROUP BY POPDATA.CITYNUM
ORDER BY COUNT(*) DESC;

In your teams, do this. Register for a free forum that gives programming advice and try to ask how to adapt the fragment of code below to show:
a) Two columns - the Filipino Population and the Total Population
b) The Filipino Population as a percentage of the total population

This was the assigned task. So we are searching for answers on how we can find a complete solution in a more understandable languange, since we're not programming majors. Thank you.
