Formula tol Neglecting the Smallest Value Across Rows

[jamesjunkers]

Say you have this table...

	A	B
1	50	50
2	45	50
3	47	50
4	50	50

I want a formula that computes the sum of column A (SUM(A1:A4)) divided by the sum of column B (SUM(B1:B4)), without including the smallest value for A. For this example, the smallest value for A is 45, so I want a formula that would basically compute (50+47+50)/(50+50+50)

Thanks

Maybe:

=(SUM(A:A)-SMALL(A:A,1)) / (SUM(B:B)-INDEX(B:B, MATCH(SMALL(A:A,1), A:A, 0))
