Memorizing the decimal and percentage conversions for common fractions is essential for speed, especially in the early parts of the test. The following table omits obvious fractions like 1/2, 1/4, etc., and focuses on those involving sixths, sevenths, eighths, ninths, elevenths, twelfths, and sixteenths. It's helpful to memorize the base fraction (e.g., 1/7) and then derive the others by multiplication.
