How to get a percentage of two fields in a query

[mdnikki]

I am trying to calculate how successful some of our appeals were but looking at the number of solicitations versus the number of responses and can't seem to figure out how to do the percentage. I would want to use the Count of Appeal (which is the number of solicitations we sent out) against the count of gift amount which is the number of responses. And possibly also see the average gift amount of each of the appeals as well. Any help is appreciated.

Appeal Description	SumOfGift Amount	CountOfGift Amount	Count of Appeal
12AAA 1stMail	$2,483,799.03	10821	26231
12AAA 1stMail - New Adds	$5,150.00	40	6252
12AAA 1stMail Sybunt	$121,463.24	828	18060
12AAA 2ndMail	$313,444.00	1734	20796
12AAA 3rdMail	$16,691.33	160	20722
12AAA DirectSolicitation	$960,012.74	233
12AAA In House Phone	$1,200.00	1
12AAA InPew	$3,030,022.69	15619
12AAA Internet	$186,370.05	433
12AAA Matching Gifts	$35.00	1
12AAA Payroll	$20,606.14	35
12AAA Phone	$209,414.00	1268
