### Instruction:
 Lexie ni miaka 6 zaidi ya ndugu yake na dada yake ni mara mbili ya umri wake. Ikiwa Lexie ana miaka 8, tofauti ya umri kati ya ndugu yake na dada yake ni ipi?


### Response:
 Ndugu yake Lexie ana miaka 8 - 6 = <<8-6=2>>2.
Dada yake ana miaka 8 x 2 = <<8*2=16>>16.
Tofauti ya umri kati ya ndugu yake na dada yake ni 16 - 2 = <<16-2=14>>14.
