I've tried the formula for calculating yeast attenuation and I must be doing something wrong. Its probably just a math mistake but I can't seem to figure this out. I'm hoping some one can help. The formula I'm using is OG-FG/OG.
Example OG 1.045- FG 1.011=.034/OG 1.045=.0325
What am I doing wrong here? I know my attenuation is not 32.5%. I've already searched but only come up with this same formula every time.

34/45 = 75.6% apparent attenuation.

Yes, you have to use whole numbers, so just use the last two of each SG.

Thanks, I knew it was something simple I was missing.
