In the U. S., 2 out of 3 high school students sleep less than 8 hours on average. Find the percent of U. S. high school students that do not sleep less than 8 hours.

33%

Step-by-step explanation:

2/3=0.6666666667 (0.7 rounded to 1.d.p)

0.6666666667*100=66.66666667% (67% rounded)

To work out 1/3 (the amount of people who don't sleep for less than 8 hours...

Either...

1/3=0.3333333333*100=33.33333333% (33% rounded)

Or...

100% (all people) - 67% (2/3 who sleep less than 8 hours)= 33%

it's both, now can you answer my most recent question?
