This technique, endorsed by the National Council of Teachers of Mathematics, makes percent conversion quick and fun.

  3. Fraction to Decimal Conversion -

    Convert any fraction to a decimal through long division; for instance, 5/8 = 0.625. University of Cambridge resources emphasize careful division and checking for repeating patterns to recognize terminating versus repeating decimals. Practice with both simple and complex fractions to master percent to decimal practice.

  4. Fraction to Percent Conversion -

    First change a fraction to its decimal form, then multiply by 100 (e.g., 3/4 = 0.75, then 0.75 × 100 = 75%). Purdue University's online math lab highlights this two-step process as the most foolproof method. Remember: "fraction to decimal, then decimal to percent" for seamless conversions.
