### Instruction:
 Mchana mmoja, Rachelle, Gretchen na Rocky walirusha noti za senti ndani ya chemchemi na kufanya maombi. Rachelle alirusha noti 180 ndani ya chemchemi. Gretchen alirusha nusu ya noti alizorusha Rachelle na Rocky alirusha noti theluthi moja ya noti alizorusha Gretchen. Jumla ya noti ngapi zilirushwa ndani ya chemchemi na wote watatu?


### Response:
 Nusu ya noti 180 ni noti 180/2=90.
Theluthi moja ya noti 90 ni noti 90/3=30.
Hivyo, jumla ya noti zilirushwa na wote watatu ni noti (180+90+30)=300.
