Dividing Fractions by Whole Numbers To Divide Fractions by Whole Numbers: Treat the integer as a fraction (i.e. place it over the denominator 1) Invert (i.e. turn over) the denominator fraction and multiply the fractions Multiply the numerators of the fractions Multiply the denominators of the fractions Place the product of the numerators over the product of the denominators Simplify the Fraction Example: Divide 2/9 by 2 The integer divisor (2) can be considered to be a fraction (2/1) Invert the denominator fraction and multiply (2/9 ÷ 2/1 = 2/9 * 1/2) Multiply the numerators (2*1=2) Multiply the denominators (9*2=18) Place the product of the numerators over the product of the denominators (2/18) Simplify the Fraction if possible (2/18 = 1/9) The Easy Way.  After inverting, it is often simplest to "cancel" before doing the multiplication. Canceling is dividing one factor of the numerator and one factor of the denominator by the same number. For example: 2/9 ÷ 2 = 2/9 ÷ 2/1 = 2/9*1/2 = (2*1)/(9*2) = (1*1)/(9*1) = 1/9 Return to Top

#### Divide the First Fraction by the Integer and Reduce to Lowest Terms

Leave the answer as a fraction, and not a mixed number
