AstroL - Word Problem

[SimplyMe]

Hi,
I can't figure out how to set up this problem.
A day on planet G lasts 10.0 hours and 39 minutes. If 37 (Earth) days have passed between two visits of a probe, how many days has it been on planet G? Give your answer to one decimal place.

I got 85.5 and it is wrong. I multiplied 37 x 24 then divided the answer by 10.39.
Then I made everything in min 639 min on G and 1440 min on Earth. Multiplied 1440 by 37 then divided by 634 and ended up with 83.4 still wrong.

10 hrs 39 min = 10 + 39/60 hrs = 10.65 hrs

"Supposed" correct answer? Wouldn't you rather know the actual correct answer?

An hour is NOT 100 minutes! 10 hours and 39 minutes is NOT 10.39 hours!

An hour is 60 minutes so 10 hours and 39 minutes is 10+ 39/60= 10+ 13/20= 10+ 13(5)/20(5)= 10+ 65/100= 10.65 hours.

Yes, 37 Earth days is 37(24) hours. Now divide by 10.65, NOT 10.39.
