    7 1/4 - 3 3/8


    = 29/4 - 27/8         ( change from mixed numeral to improper fraction )


    = 58/8 -27/8          ( Multiply the numerator and denominator of 29/4 by 2. This does not change the value of 29/4 as 58/8 is equal to 29/4 )


    = 31/8            ( 58/8 and 27/8 have same denominator 8, and 58 - 27 = 31 )


    = 3 7/8           ( Change improper fraction 31/8 to proper fraction 3 7/8 )


    = three and seven eighths      ( The answer in words )


    Please let me know if you have any further questions.
