Mayelana nalolu hlelo lokusebenza

Uhlelo lokusebenza luhlongoza izinselelo ezingama-21 ukunqoba.
Ukuthola izingxenyana ezifanele ezisohlwini phezulu kwesicelo, kunezela izingcezu ezimbili noma ezintathu zeyunithi.

Ingxenye ngayinye ehlongozwayo efanele inenombolo yezisombululo ezihlukile.
Futhi amazinga ehlukene nobunzima

Awukwazi ukuphinda izingcezu zeyunithi ngenani elifanayo.
Kuhlelo lokusebenza uzothola inkinobho yokususa zonke izixazululo ezitholakala enkingeni yamanje, futhi uqale kusukela ekuqaleni.
Ingxenyana encane kunazo zonke ezisetshenziswe kulolu hlelo lokusebenza yi-1/28.

Uhlelo lwenzelwe ukukhombisa usizo lokususa izingxenyana ukuxazulula izinkinga ezinjalo.

Icebo:
Ku-Rhind Mathematicsical Papyrus (RMP) ngonyaka we-1650 BC umbhali u-Ahmes wakopisha isivivinyo esesilahlekile manje kusukela ekubuseni kwenkosi u-Amenemamhat III.
Ingxenye yokuqala ye-papyrus inyuswa ngetafula le-2 / n. Izingxenyana 2 / n zokungafani n kusuka ku-3 kuye ku-101 zivezwa njengezibalo zezingxenyana zeyunithi.
Kulolu hlelo lokusebenza ungakha ezinye ukubola kwe-Ahmes (2/3, 2/5, 2/7, 2/9) nalabo abalahliweyo naye.
Uhlelo lokusebenza livumela ukubola futhi: 3/4, 3/5, 4/5, 5/6, 3/7, 4/7, 5/7, 3/8, 5/8, 7/8, 4/9 , 5/9, 7/9, 8/9, 3/10, 7/10, 9/10.
Ungasebenzisa ulwazi olutholakele ukuxazululwa kokubola okungu-2 / n ukuxazulula ezinye izinkinga.

Uhlelo lokusebenza "Izingxenyana Ezifanele" (unjiniyela ofanayo) yithuluzi elifanele elisiza ukuxazulula 'ukwengeza izingcezu zeyunithi'
