How do I change a decimal in to a fraction .333
stepan [7]

So in that case, it turns into 33/99

If it were 0.6667,
it would be

66/99

Phil Fresno worked 51.5 hours.
N76 [4]
So he makes 10.40 per hr for regular work, and time and a half for anything over 40 hrs.......and he worked 51.5 hrs

10.40 (40) = 416 for his regular hrs
51.5 - 40 = 11.5 hrs overtime......1.5(10.40) * 11.5 = 15.60(11.5) =
179.40 for his overtime hrs
for a total gross pay of : 416 + 179.40 = 595.40 <==

because he worked 40 hrs at 10.40 per hr...giving him $ 416...and he worked 11.5 hrs overtime at a rate of 15.60 per hr...giving him 179.40...for a total of $ 595.40 total gross pay
