I don't have a mobile but I do have a Casio fx82 Fraction calculator.
Fantastic bit of kit, works to 8 decimal places,
plus just about every mathematical function,
plus any fractional task you care to set it.
You can even get daft (but correct) fractional answers like 3791/4239
No user replaceable battery as the in-built one will last indefinitely the say
(it's already 20 years old and no sign of fading).
All for a quid from a car-boot!

The app I showed does it in 32nd 64th and the like no decimal points

It looks a very handy app for those with a smart phone.

The answer to the difficulty of fractions is (of course) to go metric.

Where's the fun in that?

I have a nice vernier which shows the measurement in decimal mm, decimal inches or inches expressed in a fraction.
Very useful for translating American plans.

I just do it all in my head or on paper or using millimetres

I just cut the first one again to match the incorrectly cut second one, then the third one.... :lol:

I'm 40 years old and went to school during the period where both metric and imperial standards were being taught. I've never been able to get on with metric myself. It just doesn't mean anything to me. For example if someone were to describe themselves as 186cm tall I'd have no idea what that means. If they said they were 6'3" on the other hand I'd know exactly what to expect. Same with kilos vs stones. I'd love to make my workshop metric free but unfortunately living in the UK today that is highly unlikely to happen and mores the shame for that IMHO. Brits invented a perfectly good set of standards and sacrificed them for who knows what reason. Probably something to do with the common market back in the 70's I suppose.
Ok sorry - rant over now!

Fractions are easy....measure in imperial and just calculate in your head.
What on earth requires an app for this is mind boggling. A more useless app I hardly conceive of. Is this like a hammer with an electric cord.

Metrication was undertaken partly to suit Europe (or at least the EEC) but also because (as I understand) it was understood by the powers that be that the USA would also abandon Imperial measurements - which of course it had no intention of doing.

There are now only 3 countries in the world that do not use the metric systems units as their official units of measurement. it is far easier to use for the average person as its base 10. and to say that imperial was perfectly good, is by the by. it's no use having a system that no-one else wants to use. we changed or units in order to be able to compete on an economic basis. Even the USA is now using the metric system more and more. i also know of a very recent NASA project that just wasted a lot of money due to the fact that half of it was measured in inches and the other mm and now the bolts are too small. also please remember that the true units of measurement used globaly for accurate measurement do not use either system any more but are now in the realms of startrek. see the thread on precision.
but then for me if its under a metre for me it's mm and if over, feet :roll:

The US of A, Liberia and Myanmar. A fact I trot out when people wax lyrical about the imperial measurement. Having said that, I am appalled our Subaru gets 15mpg and disappointed I'm 5'11" and not 6". Hearing of people measured in stones (on UK tv), takes me back to NZ in the seventies.
Although it annoys me when I read plans in inches (mainly the 3/8" stock for example), I must admit, working out 1/2 of 7/8 is pretty easy, so long as I don't need to convert it to metric.

Ii agree there [bold], however I think that the major problems for those that have been taught in a metric system when forced to use imperial units is that:
a) They are unable to form the fraction visually in their minds eye due to being taught to visualise fractions as a decimal figure or percentage of the whole
b) having that teaching constantly reinforced by the fact that they are generaly of the post pocket calculator generation (I damn you Sir Clive, to eternity on the M25 in a C5) and therefore don't (can't?) do mental arithmetic

I'm the other way round: born in the metric generation, taught metric in school...but I think in imperial, and use a combination of both for measurements!
The fractions I find easy; decimals are more problematic (0.125", 0.250" and 0.50" are no problem but what the hell's 0.71875"?)

Despite my earlier sarcastic comment I work entirely in metric. Rather in mm and meters. Those damned centimeters make no sense. Every time I am given a measurement in cm I have to convert to mm or I have no sense of what size the item is.
I am 67 so brought up in an imperial world and find the mental agility needed to measure in fractions, calculate fractions add or subtract fractions very easy. For things of some importance I always convert back to imperial as a sort of check. Its just comfortable since my sense of sizes originated there.
In 25 years the US will be completely metric as its only the old codgers who keep it alive.

I had an app like this when I was living in Canada as frations made no sense to me, but after a while I found using imperial easier than metric. Now I'm back in the UK I feel like I'm having to re learn metric. Millimetres are too long winded and I find myself having to take a moment to actually work out what the measurement is just to comprehend it, why don't we just use centemetres and metres like we were taught in school?
