The elapsed time is 9 3/4 hours the end time is 6: 00 what is the starting time

So you'll want to know some background info. 1 hour is 60 minutes so let's multiply 9 by 60 to get the number of minutes= 540 and we still have the fraction of 3/4. YAY some more background info.! 3/4 as a decimal is .75 because if you say this fraction out loud, it sounds like "three quarters" which 3 quarters is 75 cents so you can easily put any fraction with a denominator (bottom number) that is = to 4.  .75 of an hour is 45 minutes so let's add this # (45) to our original 540 minutes. it = 585 minutes  then if you minus 585 from 6:00 you'll get 9:15 so your answer is the starting time is 9:15 Hope This Helps ;D
