### Instruction:
 Kuna magari 516 katika eneo la kuegesha. Thuluthi moja ni ya bluu, nusu ni nyekundu, na wengine ni weusi. Magari mangapi ya weusi yapo katika eneo hilo?


### Response:
 Bluu = 516 * (1/3) = <<516*(1/3)=172>>172 magari
Nyekundu = 516 * (1/2) = <<516*(1/2)=258>>258
Weusi = 516 - (172 + 258) = 86 magari
