How to convert $ values? Let’s look at a true example to help us realize how important it is to know long division without a calculator! Miss Le and her friends did not have a calculator along on her trip.
This is what happened to Miss Le this August: She went shopping in Antigua, Guatemala. In Guatemala, they use Quetzales as their currency. The conversion was about 7.65 Quetzales to each US dollar. 7.65 Q = $1 7.65 Q = $1
Miss Le bought the following items (after she bartered): 1.Purse that was 120 Quetzals. About how much money was this in U.S. dollars? 2. A hand carved knife was 85Q. About how much money was this in U.S. dollars?
Steps: 1.Move the decimal from the divisor to the right until it is all the way to the end of the number. 2.Move the decimal in the dividend the SAME amount of places to the right. 3.Write the decimal on top of the “house” where you ended in the problem. 4.Divide, add Zeroes (if needed). We do not have remainders now. 5.Check to make sure decimal is in the correct location in your answer.
