    • 31/8 - 21/6 = ?
    • The common denominator of the two fractions is: 24
    • 31/8 = (3*31)/(3*8) = 93/24
    • 21/6 = (4*21)/(4*6) = 84/24
    • Fractions adjusted to a common denominator
    • 31/8 - 21/6 = 93/24 - 84/24
    • 93/24 - 84/24 = (93-84)/24
    • (93-84)/24 = 9/24
    • 9/24 = 3/8

    Solution for the given fractions

    $ \frac{31}{8 }-\frac{ 21}{6 }=? $

    The common denominator of the two fractions is: 24

    $ \frac{31}{8 }= \frac{(3*31)}{(3*8)} =\frac{ 93}{24} $

    $ \frac{21}{6 }= \frac{(4*21)}{(4*6)} =\frac{ 84}{24} $

    Fractions adjusted to a common denominator

    $ \frac{31}{8 }-\frac{ 21}{6 }=\frac{ 93}{24 }-\frac{ 84}{24} $

    $ \frac{93}{24 }-\frac{ 84}{24 }= \frac{(93-84)}{24} $

    $ \frac{(93-84)}{24 }=\frac{ 9}{24} $

    $ \frac{9}{24 }=\frac{ 3}{8} $

    $ $
