Converting 24min to Hours: True or False?

[roza-chan]

well i was wondering which of these are true and why so please help me out
24min=?h
1 min= 1/60h
.'. 24 * 1/60 =24/60 =0.4

or

1 min=1/60h
1/60=0.016161616
~0.02 (i took what is close to it)
24 * 0.02=0.48

i myself think that the second one is false but y does the number change so much??where did i go wrong?

You seem to have miscalculated the value for \frac{1}{60}.

\frac{1}{60} = 0.01666 ...

Still, it's fairly obvious where the 'error' is coming from. You've rounded the number you are multiplying by. Also as fedaykin said, you got the value for 1/60 wrong.

I suspect that it's just the 'D'OH!' moment, I have them all the time.

Never ever round down intermediate results.

Now you even know why.
