    The difference between \[4\frac{1}{2}\] and \[2\frac{1}{8}\] is ______.

    A)  \[\frac{3}{8}\]                         

    B)  \[2\frac{3}{8}\]            

    C)         \[3\frac{3}{8}\]            

    D)         \[4\frac{5}{8}\]

    Correct Answer: B

    Solution :

    \[4\frac{1}{2}=\frac{9}{2},2\frac{1}{8}=\frac{17}{8}\] Converting the fractions into like fractions LCM of 2 and 8 = 8 \[\therefore \]\[\frac{9}{2}=\frac{9\times 4}{2\times 4}=\frac{36}{8}\] and \[\frac{17}{8}=\frac{17\times 1}{8\times 1}=\frac{17}{8}\] Now, \[\frac{36}{8}-\frac{17}{8}=\frac{19}{8}=2\frac{3}{8}\]
