    Solution for the given fractions

    • 2/5 - 11/20 = ?
    • The common denominator of the two fractions is: 20
    • 2/5 = (2*4)/(4*5) = 8/20
    • 11/20 = (1*11)/(1*20) = 11/20
    • Fractions adjusted to a common denominator
    • 2/5 - 11/20 = 8/20 - 11/20
    • 8/20 - 11/20 = (8-11)/20
    • (8-11)/20 = -3/20

    Solution for the given fractions

    $ \frac{2}{5 }-\frac{ 11}{20 }=? $

    The common denominator of the two fractions is: 20

    $ \frac{2}{5 }= \frac{(2*4)}{(4*5)} =\frac{ 8}{20} $

    $ \frac{11}{20 }= \frac{(1*11)}{(1*20)} =\frac{ 11}{20} $

    Fractions adjusted to a common denominator

    $ \frac{2}{5 }-\frac{ 11}{20 }=\frac{ 8}{20 }-\frac{ 11}{20} $

    $ \frac{8}{20 }-\frac{ 11}{20 }= \frac{(8-11)}{20} $

    $ \frac{(8-11)}{20 }= -\frac{3}{20} $

    $ $
