The <em><u>correct answer</u></em> is:
They had no placeholding zero.
Explanation:
Our numbering system is one of few known to have a numeral for zero. Mayans did; however, theirs never traveled the world. Babylonians were thought to have a mark for nothing, but it was more for punctuation than numerals. Neither the Romans nor the Egyptians had a number for 0 either.
Zero is key to our system of numbering, as it helps us hold place as well as representing nothing. Without it, it is easier to represent problems in words.
So 1 hour=60 min.,
So 10/1*60/1=600 min. That means 10 hours = 600 min.,
Then add the 39 min. to this equation= 639 min.,
Then you solve for the seconds, 24/1*1/60=0.4,
So 24 seconds is 0.4 (40%) of a minute,
Then it mean that it would take 639.4 minutes for Saturn to make a full rotation.
