Using multiple "From" Locations

Hello, trying to show the percent of space used in a meter. i want to divide “space_used” from one table by the “availbe_space” from another table and *100. is there any way to do this? How do i add that second table location in the “FROM” … im using InfluxDB

SELECT (sum(“value”) / sum(“value”)) * 100 AS “alias” FROM VmStorageReport_UsedSpace
