Google Sheets Filter function w/ other function

Question

I have two columns of data, one with names (A7:A), and one with percentages (B7:B).

I am trying to use the filter function to show me the names of results with non-zero percentages. I also want to change what it spits out to have only cells in column B be multiplied by a value in a specific cell (B2) but keep column A the same.

Things tried:

=filter(A7:B,B7:B>0)

This works to filter out zero results but doesn't change column B

=FILTER($A$7:B*B2,N(B7:B)>0)

This changes column B to the desired value, but column A has #VALUE! error since it's a word and can't be multiplied by a number

=filter(A7:B,(B7:B>0)*(B7:B*B2))

This gives the right name values but keeps the original percentage values and doesn't change it.

=FILTER(A7:B*B2,B7:B>0)

This gives the right number values but gives #VALUE! error for name as it is not a number.

Answer 1

Two methods come to mind:

Array

={FILTER($A$7:A,B7:B>0),FILTER($B$7:B*B2,B7:B>0)}

Query

=QUERY(A6:B,"SELECT A, B*" & B2  & " WHERE B > 0 AND A IS NOT NULL LABEL A 'Recipe', B* "& B2 &" 'lbs'", 1)
