A whole bag of colored candles has 45 candles in it.
If 18 are red, then 27 are blue.
Blue: 27/45 = 3/5 = 0.6 = 60%
Red: 18/45 = 2/5 = 0.4 = 40%

24% of students buy there lunch, 190 students bring their lunch from home. How many students are there in total

miv72 [106K]

so we know that 24% of the students buy their lunch at the cafeteria, and 190 students brownbag.

well, 100% - 24% = 76%, so the remainder of the students, the one that is not part of the 24% is 76%, and we know that's 190 of them.

since 190 is 76%, how much is the 24%?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 190&76\\ x&24 \end{array}\implies \cfrac{190}{x}=\cfrac{76}{24}\implies 4560=76x \\\\\\ \cfrac{4560}{76}=x\implies 60=x \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{total amount of students}}{190+60\implies 250}$
