Indlela yokubala i-15% yama-60
Owu, masingene kwihlabathi leepesenti! Ukubala iipesenti kunokufana nokutyhila imfihlakalo yezibalo, kodwa ungoyiki, sikugubungele. Namhlanje ekhethekileyo: indlela yokufumanisa ukuba yiyiphi ipesenti ye-15% ye-60!
Kulungile, khawucinge ukuba unepizza enezilayi ezingama-60 (yum!). Ngoku, ukuba uthatha i-15% yezo zilayi, ufumanisa ukuba zingaphi izilayi ezenza loo ndawo. Kule meko, ijika ibe yizilayi ezi-9. Ngoko! Ngoku uyazi ukuba i-15% yama-60 yi-9.
Masifefe omnye umlingo wezibalo njengoko sijonga ezinye iipuzzle zepesenti kwilizwe lamanani:
- Ukuguqula amaqhezu ngokweepesenti: Yiba nomfanekiso-ngqondweni wokufumana ubuncwane obuneengqekembe ezixabisa amaxabiso ahlukeneyo. Ithini ipesenti yama-20 kuma-50? Kufana nokuthi ufumene i-40 kwi-100 nganye yeengqekembe ezifihliweyo!
- Ukuqhawuka iKhowudi yepesenti: Ukungena nzulu kuhambo lwethu lwamanani - yeyiphi ipesenti engama-20 kuma-80? Kuyafana nokufumanisa ukuba ezi ngqekembe zifikelela kwikota okanye ukubeka nje - ixabisa malunga nale nto ingako.
- Imilinganiselo yoBugcisa: Kunjani ngokufumana Leliphi inani kanye 10% of owuthandayo $90 bill? Ewe, ukuba isixa sokuqala sasiyi-90 yeedola - ke i-$ 9 ngokuqinisekileyo iya kumela isahlulo seshumi okanye i-10%.
Ngaba uziva unomdla? Ungayeki ukufuna kwakho imathematika apha! Qhubeka uskrola kwaye ujonge iipesenti ezingaphezulu zokubaleka ezizaliswe zizinto ezothusayo kunye nezinto ezifunyenwe ngaphambili…
Ukuqonda iipesenti kunye namanyathelo alula
Ukufumanisa ukuba yiyiphi ipesenti ye-15% yama-60, undoqo kukukhumbula ukuba iipesenti zinokubonakaliswa njengamaqhezu. Kule meko, i-15% inokuguqulwa kwiqhezu le-15/100. Xa silula eliqhezu ukuya kwelona nqanaba lisezantsi, sifumana u-3/20. Ngoku, xa siphinda-phinda 3/20 ngo 60 (emele yonke), sifumana u9. Ngoko ke, 15% ka 60 ilingana no 9 wezilayi zala pizza imnandi!
Ukuqonda iipesenti akunyanzelekanga ukuba ibe sisilayi sekeyiki enobunzima bemathematika efafazwe yonke indawo! Ngokwahlulahlula inkqubo ibe kukuluma okuncinci - ukusuka ekuguquleni iipesenti ukuya kumaqhezu kwaye emva koko ufumane ixabiso lokugqibela nge-arithmetic elula - kungekudala uza kube uhambisa izibalo ezichanekileyo zepesenti njengengcali yezibalo! Khumbula, konke malunga nokubona ubudlelwane phakathi kweengxenye kunye ne-wholes kwiresiphi yamanani-njengokwazi ukuba zingaphi iitshiphusi zetshokolethi ezenza loo ntlama ye-cookie epheleleyo. Ke qhubeleka, ucofe loo manani kwaye ukonwabele ukwaneliseka kokusombulula iipuzzle zepesenti ngokulula!
Iingxaki zokubala ngepesenti eziqhelekileyo kunye nezisombululo
Ukuphonononga nzulu kwiiconundrums zepesenti, makhe siphonononge ezinye iingxaki zokubala eziqhelekileyo kunye nezisombululo ezintle. Olunye ucelomngeni olubangel’ umdla kukukwazi ukuba ipesenti ye-15 imela ntoni kwabangama-60. Sisebenzisa ucwangciso lomlinganiselo othembekileyo apho u-x anxulumana no-100 njengo-15 enza ku-60, siphindaphinda-phinda-phinda kwaye sivule ubuncwane ukubonisa ukuba u-15 ubonisa i-25% emenyezelayo ye-trove yamanani! Ngoko! Omnye umxaki ubandakanya ukufumanisa ukuba leliphi inani elibambe imfihlelo yokuba lilingana ne-15% yama-60. Ngokumisela i-equation apho iqhezu linokumela iipesenti-i-15 kwikhulu ngalinye lombona lilingana nesinye kwisixhenxe somthamo wethu ongaziwayo-sifumanisa ukuba Inani lomlingo elizifihlayo emva kwale ntsomi asinguye omnye ngaphandle komnikelo wesisa wama-400!
Ngoku, ixesha lokujonga enye i-head-scratcher: ukubala izaphulelo! Yithi ujonge into ye-60 yeedola kunye namaphupha okuyihlutha ngexabiso elithotyiweyo. Ukuba uthanda iswiti 15% isaphulelo, imithwalo hayi, kuba impendulo ilindelwe ngezandla ezivulekileyo-ayiyo enye ngaphandle kwe-9 yeedola ezibhabhayo njengoko uqhubeka uphuma. Gcinga ezingqondweni; Izaphulelo zifana nezipho ezivela kwiijini zezibalo ezifefa umlingo wazo kwiintengiso zakho zokuthenga!
Ukuya phambili kwipesenteji yomhlaba kufuna ukuba ulola izibalo zakho zengqondo. Yonwabela iindlela ezimbini—enye apho ukutsiba okusengqiqweni kusikhokelela ekubeni sigqibe kwelokuba ekubeni i-15 ingena kakuhle kwisinye kwisine sama-60, voilà!, iziphakamisa njengokumela ikota ebalaseleyo okanye ngokulula, iguqulela ekubeni ibe sisiboniso esihle samanani ahambelanayo inomtsalane ngama-25%. Indlela yesibini ibambelela ngokungqongqo kwizithethe zemathematika ngokucalula i-equation x % phinda-phinda inani esilifunayo lilingana ncakasana nomlinganiselo wegolide esiwufunayo-ukutyhila kwakhona loo dindi yomlingo yokudibanisa amanani ngokweepesenti.
Khumbula, izibalo azipheleli nje ekudibaneni kwamanani; imalunga nokutyhila iimfihlakalo kunye nokubhiyozela amaxesha e-eureka xa iipuzzle zizisombulula ngokwazo! Ke qhubeka uphonononga, ungene nzulu kwezi pesenti zibalekayo zigcwele izinto ezothusayo ezilindele ingqondo yakho enomdla kwikona nganye yeedijiti!
