Iindlela ezininzi ukubala ipesenti yenani (kunye nohlobo olufanayo lomsebenzi)

Ukubalwa ipesenti lwenani - enye into ebalulekileyo ukuba zonke ezenzeka esikolweni kwizifundo zemathematika. Kodwa ke oku akuthethi ukuba bonke usilwe usoyise lula. Enyanisweni, umxholo ilula, eyona nto ibalulekileyo - ukwazi iindlela olungqiniweyo yokubala kwicala lonke kunye umdla yonke.

1% - inxalenye wamakhulu yonke, ukuze ukwazi eli xabiso lula ukubala indawo ixabiso. Umzekelo,-15% ka-60 kubalwa ngolu hlobo lulandelayo: thabatha 60 100 ekhulwini. Emva koko 1% - ngu 60/100 - 0.6. 15%, ngaloo ndlela, ziyila - 0.6 * 15 = 9. Oku yindlela yokuqala ukubala ipesenti inani.

Indlela yesibini - ukufikelela umlinganiselo. 15 inxulumene 100 njengoko inxulumene X-60, oko kukuthi 15/100 = x / 60. Sombulula yimalini eyenziwe ngeendlela ezimbini:

1. Kuzakuguqula yona kwi ibinzana x = 15 * 60/100. Kwakhona, kuvela: x = 9.
2. Yenza enye ukuguqulwa ngamanyathelo 2: 100x = 15 * 60, oko kukuthi, olinganise ande crosswise. Kule nkulumo, sifumana oku kulandelayo: 100X = 900. Ngoko ke, x = 9.

Ukuba ufuna ukufumana phandle ipesenti inani kwenye inombolo, ifomula nayo ilula kakhulu. Thabatha umzekelo amanani 70 no 13. Makhe 70 - yi-100%, 13 - x. Ke 13/70 = x / 100. Sombulula lo myinge inokuba iindlela esele eziqhelekileyo.

I-70 * 13 = 100; 70 = 1300; Ukuba elingqukuviweyo kwindawo yesibini wokugqibela, kuvela ukuba x = 18,57%.

Ukuba uyazi ukuba kukho ipesenti ethile yenani kwaye kufuneka ukufumana inani, kunye nale ngxaki ingasombululwa ngokupheleleyo.

Umzekelo,-16% - ngu 32. Yintoni na elipheleleyo? Kwakhona dala zinkulu: 16% enxulumene kwi-100%, kwakunye 32 ukuya x. 16/100 = 32 / x; 16x = 3200; x = 3200/16 = 200.

Ukuba imeko kukuba ingxaki ukuba inani A ipesenti ethile inani B, apho kuyimfuneko ukubala isicelo enye indlela yokubala elula kakhulu. A / B * 100% - oku kuya kuba impendulo. Umzekelo, kufuneka ufumanise ukuba ipesenti inani 87 linani 329.

Ukubala isiphumo kwifomula, sinokuyifumana 87/329 * 100% = 26,44%. Ukuba fomula olityelweyo ngexesha elifanelekileyo, ukunceda abuye ibathwana: 87 libhekisela 329, njengoko x libhekisa kwi-100%, oko kukuthi 87/329 = x / 100. Ukuguqula lo myinge, sifumana 329h = 87 * 100; 329h = 8700; x = 8700/329 = 26,44%.

Kaloku, lo ngumlinganiselo zilula phantse yonke ihlale indlebe, yaye intloko yam: isahlulo sesihlanu - yi-20%, nesahlulo seshumi - 10%, isiqingatha kunye ikota - 50% ne-25% ngokulandelelana. Kuba abathile, kuba iingcinga lula kwaye ucaca ngakumbi rhoqo, kwaye umntu lula ukusebenza ekhulwini. Umahluko omkhulu phakathi elinye ngomzuzwana ne-50% akunjalo.

Ekubeni wokubala kwaye wenze kuya kuba lula, kuba kukho nkqu iqhosha okhethekileyo ekuvumela ukuba ukubala inzala.

Kakade ke, zonke ezi misebenzi - ukukhusela theory nje. Kodwa ukubala ipesenti inani basenokufuna ebomini. On sale ukuze ubone ukuba ingaba i-30% isaphulelo ukuba ukunqakula into, okanye ke imali encinane. Ungafumanisa ukuba yintoni na ixabiso zingalujongi, kwakunye khangela nabathengisi - ngenxa yokuba kaninzi abathengi ongakhathaliyo kunye ekupheleni ithegi wentengo amanani nomtsalane kakhulu.

Bala ipesenti inani lunokufuneka, yaye ukubala kweerhafu, Kakade ke, abo ukulandelela izinto ezinjalo. Kakade ke, ukubala inzala rhoqo bajamelana ezimali, abezoqoqosho, stockbrokers kunye abahlalutyi. Enyanisweni, nkqu engaphangeliyo rhoqo kufuneka sijongane ngomdla, ngaphandle kwaye iqaphela.

Ngokufutshane, umxholo ilula, nangona kubonakala kunzima kakhulu xa efika kuqala. Noko ke, xa ufikelwa ukuqonda, imisebenzi enxulumene ukubala kwenzala inani naphezu inxalenye yonke, kubonakala imbewu. Wena nje kufuneka uzalise nesuntswana kancinane.
