Why is there only 98%

Rounding errors, I bet.

Why is there only 98%

385/703 = .54765...

285/703 = .405405...

33/703 = .046808...

[fireedud]

if ed is right, it shoud be 55%, 41% and 5%, which is 101%...

[ZeakCytho]

.54765 + .405405 + .046808 = .999863

If you carried Edbeard's numbers out to more decimal points, you'd end up with 1. But .999 is good enough for me to understand that it adds up to 1.

[oaktown]

if ed is right, it shoud be 55%, 41% and 5%, which is 101%...

so if you round them all down, it's 98%, and if you round them all up, it's 101%. Rounding does not give you accurate results, just approximate results.

And thus concludes our math lesson for today.

which is why I don't like percents, there should be a pie graph with correct angles.

I thought you were an English teacher, not a math instructor...or are they cross training you?

But really, I'm glad to see 700+ votes. I think it is safe to say that if over 1400 eyes (give or take a few pirates) have seen the Foundry in a short span like this...that must be good...even if only for a short time.

they're everybody's numbers. not just mine.

You provided them. But if you don't want the credit, I'll take it

And the whole point of this is that rounding is never the answer. Carry your decimals all the way out until the end

No, no leaving them as fractions is the most accurate.

All fractions are terminating decimals, and thus can be written as decimals with 100% accuracy. It's just a matter of going out far enough.

yes, but mistakes are more likely to happen with decimals

And not all fractions are terminating decimals, they can be terminating or repeating
