### Instruction:
 Barbi alipoteza kilogramu 1.5 kila mwezi kwa mwaka. Luca alipoteza kilogramu 9 kila mwaka kwa miaka 11. Luca alipoteza kilogramu ngapi zaidi kuliko Barbi?


### Response:
 Barbi = (1.5 * 12) = <<(1.5*12)=18>>18 kg
Luca = (9 * 11) = <<(9*11)=99>>99 kg
99 - 18 = <<99-18=81>>81 kg
Luca alipoteza kilogramu 81 zaidi kuliko Barbi.
