48 Assessment Guide for Educators: Mathematical Reasoning Appendix C a firm understanding of the reporting categories on the GED® test will help adult educators in planning how they can best help adult learners to gain the skills they will need to be successful both on the test and in the future pathway they ultimately pursue. Reporting Category 1 - Quantitative problem solving with rational numbers 25% Q.1 .a Order fractions and decimals, including on a number line. Q.1 .b Apply number properties involving multiples and factors, such as using the least common multiple, greatest common factor, or distributive property to rewrite numeric expressions. Q.1 .c Apply rules of exponents in numerical expressions with rational exponents to write equivalent expressions with rational exponents. Q.1 .d Identify absolute value or a rational number as its distance from 0 on the number line and determine the distance between two rational numbers on the number line, including using the absolute value of their difference. Q.2 .a Perform addition, subtraction, multiplication, and division on rational numbers. Q.2.b Perform computations and write numerical expressions with squares and square roots of positive, rational numbers. Q.2.c Perform computations and write numerical expressions with cubes and cube roots of rational numbers. Q.2.d Determine when a numerical expression is undefined. Q.2 .e Solve one-step or multi-step arithmetic, real world problems involving the four operations with rational numbers, including those involving scientific notation. Q.3 .a Compute unit rates. Examples include but are not limited to: unit pricing, constant speed, and persons per square mile, BTUs per cubic foot. Q.3.b Use scale factors to determine the magnitude of a size change. Convert between actual drawings and scale drawings. Q.3.c Solve multistep, arithmetic, real-world problems using ratios or proportions including those that require converting units of measure. Q.3.d Solve two-step, arithmetic, real world problems involving percents. Examples include but are not limited to: simple interest, tax, markups and markdowns, gratuities and commissions, percent increase and decrease.
