Nov 12, 2004 03:49 pm 2. Pounds to dollars - at this time there are aboot $1.89 - £1 - therefore, ist nearly double.
So just double it up and knock about 10% off the total roughly...
As for the other one...I can only coont money!! hehehe

the trivia game has got me thinking about all the things i wish i knew, but don't. maybe if anyone else has a thing like that going on, they can post thier question here; maybe someone will answer it. i'll start with 2 dumb ones that bother me that i've never been able to hold onto the method for. (sorry--bad grammar)
1. how do i convert kilometers to miles quickly in my head, and vice versa?
2. how do i convert pounds to dollars?
is there an easy way to remember this?

Nov 12, 2004 04:26 pm The pound/dollar exchange rate really does fluctuate a lot, but averages about 1.70 dollars to the pound. A mile is about 1.6 kilometers. So if you want to convert both, you're roughly on the same wavelength for either. Depends how accurate you really want to be.
Nov 12, 2004 05:06 pm agh. i kind of already know the ratio for the miles/km thing but i dont know how to quickly calculate things like that in my head.
Nov 13, 2004 03:29 pm Alright forty I'll ask a dumb question.... why do you need to convert miles to km in your head anyway? Are you trying to figure out how many miles and km long the road to the Super Bowl is? All I know about that road is that it leads through Pittsburgh..... hehehehe.
Nov 13, 2004 06:20 pm hahahah hell yeah!
actually the reason is because i'm a heavy sci fi reader. and every respectable space opera has its units listed in metric. makes it hard to visualize stuff unless i can convert.
ladies and gentlemen, i'm a dork.
Nov 13, 2004 07:10 pm Nah...really?...nah just kidding!
OK...I have a similar problem if I have to convert from metric to imperial...we're all brought up on metric here...since 1967.
It might help to have some benchmarks in mind...our speed limit in built up areas is 50 km which is about 30mi.
Open road speed is 100km...about 60mi.
And for anything else...10km is about 6mi.
I don't know now?...did that help?
Cheers,
BM :-)
Nov 13, 2004 08:59 pm yeha i have some benchmarks. i just suck at visualizing the math operations i need to do in any particular case.
Nov 13, 2004 09:00 pm like, i dont really know how to quickly and accurately get 60 percent of something in my head.
Nov 13, 2004 09:26 pm Here's what I do for sixty percent: I take half of the number, I take one tenth of the number, and then I add them together. For example, What's 60% of 420? Half is 210, one tenth is 42, therefore 60% is 252.
Works for me!
Nov 14, 2004 12:58 am there we go thats what im lookin for. it works for everyone. if that number was 423, though... :(
i've got a head full of nyquil right now and my number skills are embarassing
Nov 14, 2004 03:09 am To get 60% of 423:
10% of 423 is 42.3(move the decimal one place to the left)
For 60% then 42.3*6 or round it to 42*6
For 92% then 42.3*9.2 or round it to 43*9
Depends on whether you need it exact or not.
Though I think in the main, dexterity comes with practise...I mean if I played guitar more often than I do...which is never these days...then my fingers would be less prone to cramp and tiredness I suppose.
Guitar or manicured fingers...ah...whats a girl to do? :-)
Cheers and hoping this helps,
BM :-)
Nov 14, 2004 08:43 am Usually, you don't need to be EXACT. So with a number like 423, I call it 420 and then do as described. If I need to be exact than I use a calculator!! :-)

this is what i DONT want to do. no complex head multiplication!
i am pleased to announce that this whole problem has been resolved. i already know how to do this; i was just too lazy to figure it out, apparently. after all, i use the 10%*2 method to calculate tips in restaurants. the decimal! therefore, my solution will be to half the figure and add 10 percent.
thanks guys and bm
Nov 14, 2004 04:29 pm That was alot of work to figure out a tip for the waitress forty.
Nov 14, 2004 09:19 pm haha no no. i already knew how to do the waitress tipping, but just never put the effort into applying that same skill to km/miles
Nov 15, 2004 12:08 am Well I'm glad its all worked itself out...
Cheers,
BM
