Work Keys Practice Questions (Formula Sheet and Keys are at the end of the packet) Name ______________________________________ Prairie State Exam WorkKeys: Applied Math Section The Applied Mathematics assessment measures a person's skill in using mathematics reasoning to solve work-related problems. As a test taker, you will have to set up and solve problems like those that actually occur in a workplace. Calculators are permitted. A formula sheet will be provided. The assessment contains 33 multiple choice questions at five levels of complexity with Level 7 being the most complex. Although Level 3 is the least complex, it still assesses a level of mathematical skill well above no skill at all. The levels build on each other by incorporating the skills assessed at the preceding levels. Regardless of the skill level, most of these problems will involve one or more of the following applications. Quantity: Employees often need to determine the number of items sold, produced, or purchased, or to figure totals on a per unit basis. Money: Working with monetary units is a central part of business and is tangential to virtually every job, if in no other way than to understand a paycheck. Tasks involving monetary units include figuring sales, costs, wages and expenses. Time: Some tasks involve figuring elapsed time. Other problems are also frequently figured in terms of time ( e.g., production, sales, costs, distance, area). In many of these tasks, employees must be familiar with conversion of time units. Measurement: Calculating distance, area, weight, and volume is crucial to most work situations. Again, employees must be familiar with conversions, as well as the appropriate degree of accuracy needed for different situations. Proportions and Percentages: Proportions can be used in many tasks that require making predictions (e.g., if this is the amount for X units, how much is needed for Y units?). Percentages are used in the workplace to calculate commisions, dicounts, taxes, price increases, changes in sales, and wage changes. Averages: Many records in the workplace are expressed in terms of averages (e.g., those involving sales records, wages, costs, hours worked). These averages become tools in the decision making processes of the business. Level 3 This level measures a person's skill in performing basic mathematical operations (addition, subtraction, multiplication, division) and conversions from one form to another using whole numbers, fractions, decimals or percentages. 1.
