    Solution for the given fractions

    • 7/20 - 1/15 = ?
    • The common denominator of the two fractions is: 60
    • 7/20 = (3*7)/(3*20) = 21/60
    • 1/15 = (1*4)/(4*15) = 4/60
    • Fractions adjusted to a common denominator
    • 7/20 - 1/15 = 21/60 - 4/60
    • 21/60 - 4/60 = (21-4)/60
    • (21-4)/60 = 17/60

    Solution for the given fractions

    $ \frac{7}{20 }-\frac{ 1}{15 }=? $

    The common denominator of the two fractions is: 60

    $ \frac{7}{20 }= \frac{(3*7)}{(3*20)} =\frac{ 21}{60} $

    $ \frac{1}{15 }= \frac{(1*4)}{(4*15)} =\frac{ 4}{60} $

    Fractions adjusted to a common denominator

    $ \frac{7}{20 }-\frac{ 1}{15 }=\frac{ 21}{60 }-\frac{ 4}{60} $

    $ \frac{21}{60 }-\frac{ 4}{60 }= \frac{(21-4)}{60} $

    $ \frac{(21-4)}{60 }=\frac{ 17}{60} $

    $ $
