Step-by-Step Guide

  1. Step 1: Convert the whole number to a fraction.

    To do this, make the whole number the numerator of a fraction.

    Make the denominator
    1.For example, if you are calculating 7÷34{\displaystyle 7\div {\frac {3}{4}}}, you would first change 7{\displaystyle 7} to 71{\displaystyle {\frac {7}{1}}}.
  2. Step 2: Find the reciprocal of the divisor.

    The reciprocal of a number is the inverse of the number.

    To find the reciprocal of a fraction, reverse the numerator and denominator.For example, the inverse of 34{\displaystyle {\frac {3}{4}}} is 43{\displaystyle {\frac {4}{3}}}. , To multiply fractions, first multiply the numerators together.

    Then, multiply the denominators together.

    The product of the two fractions equals the quotient of your original division problem.For example, 71×43=283{\displaystyle {\frac {7}{1}}\times {\frac {4}{3}}={\frac {28}{3}}} , If you have an improper fraction (a fraction with a larger numerator than denominator), your teacher may require you to change it to a mixed number.

    Usually your teacher will require you to reduce proper fractions to lowest terms.

    For example, 283{\displaystyle {\frac {28}{3}}} simplified to a mixed number is 713{\displaystyle 7{\frac {1}{3}}}.
  3. Step 3: Multiply the two fractions.

  4. Step 4: Simplify

  5. Step 5: if necessary.
