Whats your guess?

calculusxy · Answer

$\text{___% of 1,200 = 9}$ 

since we don't know the percentage, i just left it blank. do you understand so far?

yes

calculusxy · Answer

so it's basically like:
$\large \color{red}{\text{Percent}} \text{ } \text{of} \text{ } \color{blue}{\text{Whole}} = \color{green}{\text{Part}}$

Hey calculusxy. Were you studying for the Hunter Entrance Exam

calculusxy · Answer

Now we can set up the proportion to solve for the percent:
$\large \frac{Part}{Whole} = \frac{Percent}{100}$ 

since we don't know the percent, it will be left as $x$ 

we can fill this proportion up by filling what we know
$\large \frac{9}{1,200} = \frac{x}{100}$ 

you can solve for $x$ in this proportion

close but incorrect...if it was 3/4 than 75% would have not attended it again and according to your question only 9 people said no so it would be alot less than 75%...

bj11684 · Answer

it is 0.75%
