Question

in a certain year at lim high school, exactly 68 out of the 400 students are taking AP chemistry. what percent of student are NOT taking AP chemistry that year?

Answer 1

68 of the 400 students take AP Chemistry. To find how many don't, subtract the total from the ones that do.

$400 - 68 = 332$

332 of the students don't take AP Chemistry. Divide 332 by 400 to get the decimal so that you can change it to a percent.

$332 \div 400 = 0.83$

To change a decimal to a fraction, move the decimal point 2 places to the right and add a percent sign.

$0.83 \rightarrow 83 \%$

83% of the students don't take AP Chemistry
