Maybe this question shouldn't be posted here, but I've always been given
great answers by some pretty bright people...so...

If I have a 37% solution of 'A'.

I need to make a solution with a final concentration of 1% by diluting
this with 'B'.


What's the math?

I think this should work

if A=1.37
B=1.00

x= parts of a
y= parts of b

1.37x + 1y = 1.01(x+y)

assume 1 part of x

1.37 + y = 1.01(1+y)
1.37 +y = 1.01 + 1.01y
..01y = .36

y = 36
x = 1
