Question

People at a party ate 25 oatmeal cookies and 40 chocolate chip cookies.
Which proportion can you solve to figure out the percentage of oatmeal cookies that were eaten? Use c, as your variable.

Answer 1

Set up the percent as a fraction of the total:
25/65 = c/100.

Solve: c = 100*(25/65) = 2500/65 = 500/13 ≈ 38.46%.
