Solve problems that require mathematical operations using mixed units (such as adding 6 feet and 4 inches to 3 feet and 10 inches, or subtracting 4 hours and 30 minutes from 3.5 hours).Convert units within or between systems of measurement (e.g., time, measurement, quantity) where the conversion factor is given either in the problem or in the formula sheet.Add and subtract fractions with unlike denominators (such as ½ - ¼).Decide what information, calculations, or unit conversions to use to find the answer to a problem.Problems require several steps of logic and calculation (e.g., problem may involve completing an order form by totaling the order and then computing tax).Put information in the right order before performing calculations.Multiply a mixed number (such 12 1/8) by a whole number or a decimal.Add or subtract fractions with a common denominator (such as ¼ + ¾ + ¼).Add commonly known fractions, decimals, or percentages (such as ½, 0.75, or 25%).Figure out simple ratios (such as ¾), simple proportions (such as 10/100 cases), or rates (such as 10 mph).For this, they may use whole numbers and decimals. Calculate the average or mean of a set of numbers (such as (10+11+12) /3 )).They can add, subtract, or multiply using positive or negative numbers (such as 10 or -2), and they can divide positive numbers (such as 10). Solve problems that require one or two mathematical operations.May include a simple chart, diagram, or graph.May include extra, unnecessary information.Information may be presented out of order.
