MATH 0930 Beginning Algebra Part 1 K.Rigdon Name___________________________ Practice Test for Exam 1 – Decimals, Sections 1.3-1.7 Due (optional) on Exam Day –Tuesday, 9/16/2014 This practice test will give you a good idea of the type and number of problems you will see on the actual test, although the number of questions is likely to be less for this exam. Working through this practice test will, therefore, provide you with a good idea of how well you know the material you will be tested over. We can go over questions on this on the Review Day (9/15) if you need. You have the opportunity to earn up to 3 extra credit points toward your test grade if you show all work possible for all the problems and, of course, get all the answers correct (answers are included for you to check your work). If you would like to earn these extra points, you will need to turn in this packet, with your work attached (done on separate lined paper), on the day of the Exam. Remember also, your book homework must be turned in on the day of the test – so have it ready when you arrive.
