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
