Indlela yokubala ipesenti yohlahlo-mali?

Uluntu kudala lubekhona, ukubala indlela ipesenti le mali. Eli gama livela kwisiLatini «pesenti», enyanisweni, ngolwimi IsiNgesi olunjalo, washiya. "Percent" - ngokoqobo "omnye ekhulwini". Igama iyafaneleka kakhulu, ngenxa yokuba lo mbono kanye elinye ekhulwini le mali. Ukuba ngaba ulibele lesayensi lesikolo kwaye ufuna ukuqonda indlela isabelo inani, yithini, 280.550, kufuneka nje ukuba alabe libe nekhulu (okanye isiphumlisi kumanani ezimbini kufutshane phezulu). Ngenxa yoko, sifumana 2 805.50. Ngaba uyazi ukuba bangaphi isixa ngasentla kuya kufikelela ekhulwini ezintathu? elula kakhulu: phinda wamakhulu omnye (kulo mzekelo 2 805.50) ukuya kwemithathu. Kungcono ninikane 8 416,50.

Njengoko ubona, kulula kakhulu. Ukuba akwenjinjalo ukufumana engqondweni yakho ukuze wenze inkqubo yokwahlula amanani original 100 nande isiphumo soko ngenani elithandekayo umdla, kukho omnye, ilula kakhulu, indlela ukubala indlela umdla. Ngokuqhelekileyo esandleni indoda mihla kusoloko isixhobo sokubala. On imifanekiso ezininzi isixhobo becomputing unalo icon ethile kumaqhosha amanani, kwaye omnye wabo uphawu '% ". Nalo eli qhosha nkqubo vyschityvaniya ayifuni ukuthatha imizuzwana ngaphezulu ezimbini. Masithi ufuna ukwazi indlela ziya kuba 7% 550 bagaywa wokubala 550, yaye emva koko Sehla iqhosha "x" (ukwanda), kufuneka utsalele umnxeba-7, uze emva koko, endaweni yokuba i "=" icon, ucofe isitshixo '% ". On ibhodi kukho yoko: 38.5.

Kodwa ngamanye amaxesha kufuneka sifunde akukho indlela ukubala ipesenti yohlahlo-mali, kodwa koko, yintoni ipesenti inani omnye elomnye. Nanku umzekelo olula: amanani amabini - 1100 yaye 253. Yeyiphi ipesenti wenza 253 inani lilonke ngo-1100? Ukuze ubale oku, kufuneka ukuba phinda inani elincinci (253) 100, yaye isiphumo wahlulwe yi inombolo enkulu (1100). Kubonakala-23%. Ngamanye amaxesha kufuneka ukubala inani thabatha elinye ekhulwini. Amaxesha amaninzi kufikwa kwimivuzo. Uyazi na umvuzo, kodwa umdla ukwazi indlela bafumane izandla zenu, emva kokuba isixa mali yerhafu ithathe lomvuzo. Ukufumana kwi wokubala imali yomvuzo, nqakraza kwi icon "-", uze ufake inani hundredths loo ntlawulo karhulumente njengoko irhafu, kwaye nqakraza kwi "%".

Indlela yokubala ipesenti yohlahlo-mali, kusetyenziswa inkqubo ye-Excel? Kwikholam, apho sifuna nakuzisiza olifunayo%, kufuneka ufake uphawu "=", ngoko ke inani kuso ubale ipesenti, ngoko ke uphawu lophindaphindo, yaye ekugqibeleni, inani hundredths ngayo. Emva koko cofa «Ngena», yaye isiphumo livela kwiseli. Ecacileyo, sinikela umzekelo: = 1750 *, 48,%, Ngena. Phambi kokuba ukusebenza, kufuneka uqwalasele i nkqubo yobalo: cofa i ekhohlo iqhosha le mouse kwi kwiseli.

Abantu bakude izibalo kubomi babo bemihla ngemihla, ngokufuthi kuthengwe nomtsalane, kuzo umntwana, iintlawulo phantsi mboleko ebhankini okanye zosetyenziso lwemboleko iivenkile badla rivaleleke. Indlela yokubala ipesenti-mboleko kakuhle? Asimele arithmetically kuphela ukubala imboleko, kodwa uphinda-mali kwi isixa sexesha (iintsuku, iinyanga, iminyaka), apho kokuba ikhutshwe. Ngokomzekelo, ukuba ufuna ukuthenga imoto uthabathe ebhankini 150 amawaka kwi-13% ngonyaka kangangeminyaka-5. Kangakanani kufuneka uhlawule kwiziko yezimali ngexesha kwiminyaka emihlanu? Sikholelwa: 150 000 x 13% x 5 s = 97 500 (kwaye inzala kuphela). Kule mali kufuneka kongezwe ityala ngokwawo: 97,500 + 150,000 = 247,500.

Ngoko ke musa bathenge izithembiso amazinga enzala asezantsi kakhulu, kwaye ke kufuneka ukuba bahlaziye yonke into yaye babale intloko yakho okanye sokubala. Hayi ilize bagcini kumaXesha Aphakathi laqulunqa izintlu yonke entsonkothileyo ebonisa ukuba ukubala indlela ipesenti yesixa elinikwe mboleki. Ezi Ubalo kuqala declassified kuphela ngo-1584. Waye endleleni, ngaba uyazi apho ivela i icon enjalo, okuthetha ipesenti - '% "? Ibonakele ejikelezayo kuphela ngo-1685 ngoncedo ... ukubona elula. Ngoxa e Paris, yanyatheliswa "Guidelines for Mathematics zorhwebo" abafundi-abarhwebi. Typewriting indiva waza wafumana ngokubanzi de ekupheleni kwenkulungwane XVII iisimboli «cto», leyo imela isahlulo sekhulu, toe ezimbini ezincinane, ezahlulwe isleshi. Kwacaca%. Kwaye ekubeni le ncwadi, isizukulwana esitsha ngabarhwebi bakuthabatha icon elinikiweyo.
