### Instruction:
 Norma anachukua nguo zake kwenye kusafisha. Anawaacha fulana 9 na mara mbili ya idadi ya sweta kama fulana kwenye mashine ya kuosha. Anaporudi anakuta sweta 3 na mara tatu ya idadi ya fulana. Nguo ngapi zimepotea?


### Response:
 Idadi ya sweta ambazo Norma alizipeleka kwenye kusafisha ni 9 * 2 = <<9*2=18>>18
Aliporudi, alikuta fulana 3 * 3 = <<3*3=9>>9
Jumla ya nguo ambazo Norma alizipeleka kwenye kusafisha ni 9 + 18 = <<9+18=27>>27
Jumla ya nguo ambazo Norma alizikuta ni 9 + 3 = <<9+3=12>>12
Nguo ambazo zimepotea ni 27 - 12 = <<27-12=15>>15
