another fraction word problem
I tried to figure out this question..and started it, but do not know how to continue....would anyone we able to give me a hand ??
An airline passenger read for the first 1/9 of the flight, and watched the film for the next 8/15 of the flight. He managed to sleep for 3/4 of the remaining time. When he woke they were serving snacks, which filled another 20 minutes. After that there was only 1/45 of the total flight time left. How long did he sleep?
Would anyone be able to draw a simple diagram...to explain this?
I tired looking for the common denominator by adding all the fractions together..
then i dont know what to do ><
