### Instruction:
 Katika mkutano wa familia ya Johnson, kulikuwa na watoto 45 na watu wazima theluthi moja ya idadi hiyo. Watu wazima theluthi moja walivaa bluu. Watu wazima wangapi hawakuvaa bluu?


### Response:
 Watu wazima theluthi moja ya idadi ya watoto ni 45/3=<<45/3=15>>15 watu wazima.
Theluthi moja ya watu wazima walivaa bluu, au 15/3=<<15/3=5>>5 watu wazima walivaa bluu.
Hivyo, watu wazima 15-5=<<15-5=10>>10 hawakuvaa bluu.
