Izibalo school. Indlela yokuthola iphesenti inani

Igama elithi "inzalo" ngesiGreki lisho ingxenye eyodwa wokuhamba inombolo. Esifundweni sezibalo, futhi emhlabeni, kubhekwa ukuba ngokuphelele 100%. Kususelwa kule isimiso, wakha imithetho Computing.

Kunezindlela eziningana ongakhetha kuzona ukuze ukwazi ukuhlangabezana nemisebenzi ehambisana ngenhloso ukubala iphesenti inani. Umsebenti ngamunye onjalo siqu umqondo ngabanye izixazululo zayo.

Thola iphesenti inani

Isitatimende inkinga kunikezwa inani elithile ezinombolo liyadingeka ukuze uthole iphesenti yayo. Ngokwesibonelo, sinalo inombolo 47, futhi kubalulekile ukubala 25%.

Isixazululo: Ukuze ukuxazulula inombolo yokuqala samukela 100%. Ngemva kwalokho, le iphesenti lihunyushwe idesimali futhi ukuthola ukuthi 25% = 0.25. 47 iyanda ngephesenti elisetshenziswa Kudutshulwe ukuthola inombolo oyifunayo 47 * 0.25 = 11.75.

A: 11,75 kuyinto 25% isibalo 47.

Thola inani iphesenti

Olunye uhlobo izinkinga ezihlobene umbuzo kanjani ukuthola iphesenti inombolo ekubalweni ukubaluleka kokuba amaphesenti. Njengoba sazi ukuthi 57 kuyinto 45% kwenani elithile. Kuyadingeka ukuthola inombolo.

Isixazululo: Ukuze uxazulule le nkinga, kubalulekile ukuba kwahlukaniswe itholakale iphesenti ukuthi kusukela lonke. Ngakho, sithola ukuthi 57 / 126.67 = 0.45. Ukuze uqonde kangcono lesi senzo ngeke kube aphume endaweni ukwenza out lonke inqubo ngokuningiliziwe. 57 - 45% ke, ngamafuphi ukuthola ukubaluleka iphesenti eyodwa, inombolo kumele zihlukaniswe inani isithakazelo. It kuvela ukuthi 1% wayo yonke inombolo ilingana 1,2667. Ngokulandelayo, ukubaluleka ukuthola lonke, sisuke okuholela iyanda yi-100.

Impendulo: Inombolo, 45% okuyinto 57, ilingana 126,67.

Thola ukuthi yini Iphesenti inombolo eyodwa lomunye

Kancane nzima okufakiwe imisebenzi kudingeka uthole ukubaluleka iphesenti ukuthi inombolo eyodwa ukusuka kwenye. Indlela yokuthola iphesenti inani kuleli cala? Impendulo silula. Cabangela isibonelo ilila. Sine izinombolo ezimbili: Ake sithi lo 45 futhi 58. Ukuze uthole ukuthi yini Amaphesenti angu 45 we-58 ezidingekayo ukuze wande ngu-100 futhi ukuhlukana ngokuhlela 58. Sithola ukuthi 45 - kungcono 77,6% we 58.

Ngokuvamile, uyakwazi ukubona uma ubhekene nesimo esinjena lapho abantu abaqondi ukuthi ukushintsha intengo umkhiqizo, uma ukuba anyuke ngenxa 15%. Abantu ukhohlwe aphansi mathematics esikoleni futhi ngenxa yalesi sizathu uyazibuza kanjani ukuthola iphesenti inani.

okuthunyelwe ezibalulekile Ikakhulukazi angu ulwazi emkhakheni wezokuxhumana futhi exchange imisebenzi. Ngokwenza esisemanzini akhawunti yasebhange, siphinde iphatha isithakazelo. Kukhona ngokuvamile isimiso amaphesenti elintantayo noma osonhlamvukazi, kancane inkimbinkimbi isimiso yokusebenzisa ikhompyutha ngomphumela wokugcina.

Njengoba singabona, nge ukuphindaphinda kancane, ungakwazi ukukhumbula kalula noma uphinde ufunde indlela ukuthola iphesenti inombolo, futhi bebonke, kanjani ukusebenza iyunithi efana zezibalo kanye zezimali. Lolu lwazi ngeke kuphela ukwandisa umbono womuntu jikelele, kodwa futhi kuyosiza ukugxila eqiniseka kakhudlwana ezimweni nge izinguquko amanani, exchange rate, ibhange isithakazelo, inzuzo engenayo kanye nezinye izinqubo kubaluleke kakhulu. Yiqiniso, Uma unganakile kubonakala sengathi ikhono ukubala engqondweni kwakhe kungasindisa ukuphila imizuzwana embalwa, kodwa ukunqoba umzuzu ekuthatheni isinqumo kungaholela izinsuku abakhululiwe ngaphezulu ngonyaka.
