Bloody Hell! Am I glad I didn't need to employ an accountant (or one or two forum members above) to work out my VAT figures. 105ml + 5% = 110.25ml therefore the 5% of 105ml = 5.25ml. FFS!.
Youre initial sum is correct arquey. But 5ml of 105 is 4.76%. I'm no mathematician, but 5/105, which is a fraction of the whole is 4.76%. You cannot escape the math (stated this way to annoy shadow). However I too see the confusion and would like to understand why or how it occurs.
The proposition was that you have 105 ml of mixture, of which 5 ml is alcohol and 100ml is water. When you express this as a % you are translating the 105 to the same ratio as if the total volume was 100 So 5 in 105 is the same ratio would be 4.8 in 100.
Ah-ha, so that's what you are doing - well that's not what my original figures at Post 26 were about - I have edited that post to make it simpler. Takes me back to working out how much the 17.5% VAT element was of the total purchase price when the initial VAT charge hadn't been shown on the invoice. That way I tend to agree with the under 5%-ers. But actually I didn't care about the VAT in the end, because although I had to charge 17.5% and 20% respectively; I only had to pay the VATman 9% and 11.5% anyway; because I had negotiated a Flat Rate based on the type of my business. The daft thing was that all my clients were Zero rated, so the VATman got sod all.
No it wasn't - all I was saying was that the constituents of the mix were 5ml to 100ml; IE 5% to 100% IE: a ratio either way you look at it.
5% of 105 is 5.25. To calculate 10% of 105, simply move the point back one place to make 10.5. 5% is half of 10%, so divide 10.5 into two to make 5.25%. On a calculator, tap in 105x5x%=5.25
You are both largely right, and just a little wrong. OR - your calc is mathematically correct in response to Boots but does not calculate the % (proportion / ratio) represented by 5ml of alcohol in a mix of total 105ml volume, which is what was originally proposed. Boots- your calc is correct to solve the question but you expressed the answer wrongly - you said 5% of 105 is 4.76. It isn’t, it is 5.25. However, 5ml of alcohol in a 105ml mix with water is 4.76% alcohol.

May I make a suggestion? If you are not too good at maths and struggle with percentages, don't keep it to yourself - please post all your attempts on here, and give others a good laugh.
actually Jon (ignoring Pete) I said 5ml alcohol of the 105ml total is 4.76%. (i edited my mistake heheh, I meant 5ml)
Or to one decimal place - 4.9% and 95.1% But who really gives a FF when it wasn't the original point? There would still be twenty times more water than alcohol; even if it had mixed.
