Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
 Tim ana umri wa miaka 5. Binamu yake, Rommel, ana umri mara tatu ya yeye. Binamu yake mwingine, Jenny, ana umri wa miaka 2 zaidi ya Rommel. Tim ana umri mdogo kwa miaka mingapi kuliko Jenny?


### Response:
 Rommel ana umri wa miaka 5 x 3 = <<5*3=15>>15.
Jenny ana umri wa miaka 15 + 2 = <<15+2=17>>17.
Hivyo, Tim ana umri mdogo kwa miaka 17 - 5 = <<17-5=12>>12 kuliko Jenny.
