A baker made 81 onion bagels one morning. The onion bagels were 45% of the bagels she made. How many bagels did the baker make? Use the Percent Formula to solve the problem. LaTeX: \frac{\%}{100}\:=\:\frac{Part\:\left(is\right)}{Whole\:\left(of\right)}
Let b represent the total number of bagels made. Then 0.45b = 81, and b = 81/0.45, or 180 bagels total. Note that that "45%" must be converted into the decimal fraction 0.45 here.
