    Answer:

            Relative frequency

            0.214

            0.268

            0.446  

            0.071

    Total  1

    Step-by-step explanation:

    The relative frequency is computed by dividing the individual frequencies to the sum of frequencies.

    sum of frequencies=12+15+25+4=56

    Class     Relative Frequency

    10-20       12/56=0.214

    20-30      15/56=0.268

    30-40      25/56=0.446

    40-50      4/56=0.071

    Total         12/56+15/56+25/56+4/56=56/56=1
