### Instruction:
 Ivanka aliandika kitabu ambacho kilimchukua miezi 3 zaidi kuliko ilivyomchukua Woody kuandika kitabu. Woody alitumia miaka 1.5 kuandika kitabu chake. Jumla ya miezi wangapi Ivanka na Woody walihitaji kuandika vitabu vyao?


### Response:
 Woody alitumia miaka 1.5 kuandika kitabu chake, ambayo ni miaka 1.5 * 12 miezi/mwaka = <<1.5*12=18>>18 miezi.
Ivanka alitumia 18 + 3 = <<18+3=21>>21 miezi kuandika kitabu chake.
Jumla ya muda wa kuandika vitabu vyote ni 18 + 21 = <<18+21=39>>39 miezi.
