# American Creativity Academy Practice Packet ## **Practice Packet Instructions** This practice packet is only meant to be a strong study and practice guide for the exam. These questions are not meant to be the same ones that will appear on the exam, but you will receive similar questions. All questions are meant to be a guide, and answers will not be directly provided for these questions unless solved in class with the teacher. These questions will also demonstrate the format of the different type of questions that will appear on the exam (for example: multiple choice, fill in the blank, long answer etc.) Please ensure you study well, get lots of sleep before the exam and ask questions. If you familiarize yourself very well with this practice packet, you will be set up for success for the upcoming exam. ## **Review Sheets** ### **Question 1 - Multiple Choice** 1. 750000 mg = ______ Kg - a) 0.75 - b) 7.5 - c) 75.0 - d) 0.075 2. 0.1 cm = ______ mm - a) 100 - b) 10 - c) 1 - d) 0.01 3.
