Kodi kuwerengera ndi kuchuluka

Mudziwa kuwerengera kuchuluka kwa chiwerengero kungakhale kothandiza osati kwa ophunzira akusekondale. Tsiku ndi tsiku, luso limeneli chofunika kuwerengera malipiro ngongole, kuwerengera ndi muone ngati akanatha kudziwa zoona mtengo mlandu msonkho pa chiphaso cha malipiro. Ndi antchito ambiri zosiyanasiyana makampani ndi mabungwe ang'onoang'ono ndi luso kuyesetsa basi.

Kodi izo - kuchuluka? aliyense pulogalamu sukulu amakumbukira kuti mu dziko kuchuluka ndi imodzi-zana mbali ya chilichonse. Ndiko mawu ena, mawu akuti "3 peresenti" ayenera kumvetsa 3 hundredths wa nambala iliyonse. anthu kulemba ndi kufupika anavomereza zoti mawu "peresenti" chizindikiro "%".

Ndipo kusukulu ife tonse tikudziwa mmene kuwerengera kuchuluka kwa chiwerengero: chiwerengero lagawidwa ndi zana, kupeza phindu la gawo limodzi, ndiyeno quotient chifukwa ndi kuchulukitsa ndi chiwerengero kusonyeza kuchuluka chidwi kuti muyenera kupeza.

Mwachitsanzo, m'pofunika kudziwa 28% ya 500. Mfundo ayenera kukhala motere:

1. Ife tikupeza kukula kwa 1% ya 500 magawano.

500: 100 = 5

1. Ife tikupeza chiwerengero anakonzeratu akamagwira kuchulukitsa ndi quotient ndi 100.

5 X 28 = 140.

Ndiko kuti, 28% ya 500 - ndi 28/100 500. Mu njira ina, mukhoza kulemba zimenezi:

500 × 28/100 = 140.

Choncho mmene kuwerengera kuchuluka kwa chiwerengero si kophweka mu malingaliro anu, ndi cholembera ndi pepala pafupi si kulikonse, koma ambiri lerolino ntchito toŵerengera.

Pakuti mawerengedwe akhoza kugwiritsa ntchito njira tafotokozazi: anakonzeratu chiwerengero cha zana ndi kugawidwa ndi kuchuluka chofunika kuchulukitsa peresenti.

Pali kuthekera aziwerenga mofulumira:

1. Mu Chiwerengero analowa nambala anakonzeratu. Ifeyo - 500.
2. Kenako atolankhani "kuchulukitsa".
3. Ndiye dials chiwerengero cha chidwi chofunika - kwa njira zathu ndi 28.
4. M'malo mwa kulingana chizindikiro pa Chiwerengero kusankha%.
5. Ife tifika zotsatira - ndi 140 muchisanzo chimenechi.

Ndipo mmene kuwerengera kuchuluka kwa chiwerengero pa kompyuta, pogwiritsa ntchito mawerengedwe ntchito mu «kupambana» pulogalamu? Ndi ndondomeko mwachilungamo wophweka.

1. Mu selo kuti amasonyeza Calculated kuchuluka ofanana chizindikiro kulowa "=".
2. Kenako, anakonzeratu chiwerengero cha opezeka, amene kuyang'ana kwa kuchuluka kapena "adiresi" selo, kumene chiwerengero kale analowa. Ife, mu chitsanzo chathu, ife timathandiza chiwerengero 500.
3. Chachitatu ndi kusaina nomination ndi "kuchulukitsa" kapena "*".
4. Tsopano ife azilemba nambala yomwe nambala chidwi chofunika. Pakuti ife ndi 28.
5. Chinthu penultimate ndi oyamba a chizindikiro "kuchuluka", ndiwo wa mawonekedwe "%".
6. Kuti chifukwa inu akanikizire batani pa kiyibodi «Lowani». Zotsatira - 140 - sadzakhala pang'onopang'ono kuonekera pa polojekiti ndi.

Musanayambe pulogalamu "kupambana" kusiyidwa mbewa batani kuika mu maselo a tebulo mtundu yoyenera kapena kugwiritsa ntchito "Menyu", "Mtundu - Maselo - Numeri -. Chidwi"

Mwachitsanzo Reflux mmene kuwerengera kuchuluka kwa chiwerengero, ndi njira kupeza angati peresenti ya nambala wani ndi mzake.

Mwachitsanzo, timapatsidwa manambala 140 ndi 500. Funso Choncho: ndi kuchuluka 140 500?

1. Choyamba, tiyenera kupeza chimene gawo limodzi ndi 500. Zimenezo, tikupitirira okalamba ndi kugawaniza dera 500 kupeza 100. 5.
2. Tsopano tili kupeza angati peresenti munali chiwerengero anakonzeratu za 140. Kuti tichite zimenezi, muyenera kugawa 140 ndi 5. Tiyenera kupeza yemweyo 28 peresenti!
3. njira kwa mawerengedwe uyu akhoza kulembedwa motere:

140 (500: 100) = 140: 500/100 = 140: 500 X 100 = 28.

Ndiko kuti, chiwerengero cha 140 ndi 500 ndi 28 peresenti.

Kuti tipeze kuchuluka nambala wani ndi mzake, tiyenera kugawa ochepa kwambiri payekha ndi kuchulukitsa ndi 100.

maluso awa ndi amalonda ovuta amene zikugwira ntchito. Pamene wakhala mitengo katundu zambiri zimafuna luso, mmene kuwerengera kuchuluka kwa chiwerengero monga kufunika "kunyengeza" pa mankhwala ntchito zimenezi. Njira yabwino kwambiri kuti uthunthu wonse wa wakunyengeza mofanana kuchuluka, mwachitsanzo 15%.

Koma kwa mawerengedwe a zopeza asanachotse ndi zinthu zina zofunikira. Mwachitsanzo, ndalama tsiku mu khola anali 3450 rubles. Kodi ndalama khoka ku katundu anagulitsa? Ena amalonda wokhala naively kuwerengetsa 15% ya ndalama lalikulu ndi kulakwitsa kochuluka! Pochoka makope njira Choncho cholakwika "kunyengeza", ndipo iwo kukhala ndi kukanda mitu yawo, kumene kunali kuchepa.

Ndipo zonse lophweka. Pambuyo kuzimata mankhwala sanali azipereka 100% wa mtengo wake, ndi 100% + 15% = 115%. Choncho, kupeza Uwerenge chimaposa anawonjezera phindu, 15% kuchita masamu motere:

1. Pali 1% ya ndalama, osati nagawira izo ndi 100, ndi 115. Zimenezo, mu nkhani iyi,

3450: 115 = 20

1. Ndipo tsopano mungathe kufufuza anawonjezera phindu kuti akhoza kukhala molimba mtima akuchotsa kufalitsidwa.

20 X 15 = 300

Chiwerengerochi atengedwa "kwa denga", choncho usakhale kwambiri za deta izi. Koma njira okha kuwerengetsa kulandira chithandizo, iwo alibe zolakwika.
