The question was
The shaded region of the strip diagram represents the number of students that
get more than 9 hours of sleep each night. Of the students surveyed, 45 get less
than 9 hours of sleep each night. How many students were surveyed?
2 out 5 is shaded (I hate posting pictures)
Don't worry, I'm so bad with tech too.
My friends always have to teach me by sending screenshots with arrows drawn on where to click.
*I'm gonna start by assuming that no students got exactly 9 hours of sleep that night
So 2/5 of the students get more than 9 hours of sleep each night.
That would mean that 3/5 of the students got less than 9 hours of sleep each night.
If 3/5 of the students is 45, what's the total amount of students?
3/5x = 45
x = 45*5/3 = 75.
So our answer is 75. :))
I hope this helped.
