Chii kubva muzana? Fomura muzana. Pauwandu hweavo - sei kuverenga?

Nhasi munyika yemazuva ano haagoni kuita pasina mubereko. Kunyange kuchikoro, kutanga giredhi 5, vana kudzidza pfungwa uye kugadzirisa zvinetso zvikuru ichi. Kufarira inowanikwa zvose zvoupenyu zvivako ano. Somuenzaniso, mabhengi, chikwereti mari overpaid kunoenderana kwakakura kondirakiti; pamusoro mari divi zvakare inokanganisa mashoko chimbadzo. Saka zvinokosha zvakakodzera kuziva chii kubva muzana.

Pfungwa mubereko

Maererano nerimwe ngano, kuti kubva muzana aibva typo benzi. Compositor akanga aisa nhamba 100, asi hwakakanyiwa uye akaisa sezvinotevera: 010. Izvi kwaiva chikonzero kuti zero ikakuruma wokutanga kumutswa uye mumwe kutura. Unit ikava backslash. manipulations akadaro kuti paiva muzana chiratidzo. Chokwadi, pane dzimwe ngano nezvemavambo zvikuru ichi.

About muzana vaHindu aizivikanwa V remakore. MuEurope decimals, iyo hunonyatsobatana pfungwa yedu yakabuda shure chemakore. Kokutanga muTestamende World mutongo pamusoro chii kubva muzana akapinda musayendisiti kubva Belgium Simon Stevin. Muna 1584 zvakanzi yakatanga kubudiswa tafura netsika masayendisiti izvi chete.

Shoko "kufarira" rine yakatangira mumutauro wechiLatin somunhu aifarira ane zana. Kana isu kushandura mashoko, iwe kuwana "zana". Saka, pasi kubva muzana zvinoreva chimwe ramazana ane zvikuru nhamba. ukoshi Izvi zvinoratidzwa chiratidzo%.

Nokuda kutifadza mukana enzanisa zvikamu rose pasina dambudziko. Chimiro mbambo zvikuru nyore dzemaitirwe, saka vava nevakawanda.

Translation zvikamu zviduku kuti pauwandu hweavo

Kutendeutsa grade kuti pauwandu hweavo kungadiwa vanonzi yokuita mhindu kuti chikamu chiduku zvikawanda ne 100% iri anonzi mugumisiro.

Kana uchida exchange kuti chikamu zvikamu, zvakafanira kutanga kuita grade, uye ipapo kushandisa pamusoro payakavakirwa.

Translation muzana chakapatsanurwa

Zvazvakadaro, ari nzira muzana pane hama. Asi iwe unofanira kuziva sei kushandurira kukosha ichi munzvimbo fractional okuti. Kutendeutsa mugove (kubva muzana) muna decimals, zvakakodzera kubvisa% chiratidzo uye kugoverana nhamba 100.

The yokuita pakuverenga ari chikamu uwandu

A bvunzo basa kemisitiri ane "wakanakisisa" vakagamuchira 30% vadzidzi. Total Vadzidzi 40 mukirasi. How vadzidzi vazhinji vakanyora emibvunzo pamusoro "5"? Basa iri zvinoratidza sei kuti azive kuti chikamu kuwanda.

mhinduro:

1) 40 X 30 = 1200.

2) 1200: 100 = 12 (vadzidzi).

Mhinduro: bvunza pamusoro "5" akanyorwa nevadzidzi 12.

Unogona kushandisa wakagadzirira akagadzirwa tafura Rinoratidza zvimwe zvikamu zviduku uye pauwandu hweavo kuti anoenderana navo.

Zvakaratidza kuti nzira muzana nhamba iri sezvinotevera: C = ^{(A ∙ B)} / _100, apo A - nhamba chepakutanga (ari muenzaniso chaiwo akaenzana 40); B - yakawanda mubereko (iri basa B = 30%); C - zvinodiwa mugumisiro.

Formula Anoverenga kubva muzana

Rinotevera basa acharatidza chii kubva muzana uye sei kuwana nhamba iri kubva muzana.

Nguo fekitari yakabereka 1,200 madhirezi, idzo 32% - mutsva rokwe maitiro. itsva werudzii madhirezi vangani kugadzirwa nguvo fekitari?

mhinduro:

1. 1200: 100 = 12 (s) - 1% mishonga zvose anobudiswa.

2. 12 X 32 = 384 (nemapfekero).

Mhinduro: The fekitari yakabereka 384 madhirezi wokugadzira itsva.

Kana zvakafanira kuti kuwana nhamba yaro kufarira, shandisa mutoo: C = ^{(A ∙ 100)} / _B, apo A - uwandu zvinhu (kana ichi A = 1200); B - yakawanda mubereko (zvikurukuru basa B = 32%); C - USINGAZIKAMWI uwandu.

Kuwedzera, kudzikira nhamba zvakafanorongwa nhamba muzana

Vadzidzi vanofanira kudzidza kuti kufarira kwakadaro ndiko kufunga navo uye kugadzirisa zvinetso-siyana. To ichi anofanira kunzwisiswa se kuwedzera kana kuderedza nhamba pa N%.

Kazhinji vapiwa basa, uye muupenyu zvinokosha kuziva chii nhamba chete, yakawedzera yakati uwandu kufarira. Somuenzaniso, vakapiwa kuwanda H. Tinofanira kuziva chii kunokosha X, kana zvibereko, uti, 40%. Chokutanga zvakafanira kushandura 40% fractional nhamba (40/100). Saka, nemhaka kuwedzera uwandu X achava: X + 40% X = ∙ ^{(1 + _40/100)} ∙ X = 1,4 ∙ X. Kana X pachinzvimbo kuti kutsiva chero nhamba, tora Somuenzaniso, 100, ipapo yose mashoko achava akaenzana : 1,4 ∙ X = 1,4 ∙ 100 = 140.

Inenge chete musimboti uye rinoshandiswa kudzikira nhamba akafanorongerwa nhamba muzana. Zvakakosha kuita Masvomhu: X - X = 40% ∙ X ∙ ^(1-40 / ₁₀₀₎ = 0,6 ∙ X. Kana mutengo iri 100, ipapo 0,6 ∙ X = ^0,6. 100 = 60.

Pane mabasa apo unofanira kuziva, nhamba mangani muzana.

Somuenzaniso, imwe basa mutyairi akatasva mumwe mugove nzira ari kumhanya 80 km / h. Pane imwe nzvimbo pamusoro chitima nokukurumidza yakawedzera kusvika 100 km / h. By chii kubva muzana yakawedzera nokukurumidza pamusoro chitima?

mhinduro:

Tambira 80 km / h - 100%. Zvadaro tinobudisa Masvomhu: (100% ∙ 100 km / h) / 80 km / h = 1000 8 = 125%. Zvakaratidza kuti 100 km / h - zviri 125%. Kuti uzive sei kuwedzera nokukurumidza, zvakakodzera exchange: 125% - 100% = 25%.

Mhinduro: 25% kuwedzera nokukurumidza zviri chitima rechipiri chikamu.

chikamu

Kune zviitiko kana zvakakodzera kuti zvinetso mubereko, uchishandisa zvinoenderana. Kutaura zvazviri, nzira iyi kuwana mibairo pamwero mukuru kunoita kuti zvive nyore vechikoro, vadzidzisi uye kwete chete.

Saka, chii chiri kuwanda? Iri izwi rinoreva wakaenzana ukama maviri kungaratidzwa sezvinotevera: ^A / _B = ^C / _D.

In masvomhu mabhuku akanyorwa ushe: zvibereko yokunyanyisa nhengo wakaenzana zvibereko avhareji. Izvi kunoratidzwa anotevera nzira: D = A X B X C

With Pfungwa iyi, zvinokwanisika kuverenga chero nhamba kana dzimwe nhengo nhatu kukura anozivikanwa. Somuenzaniso, A - USINGAZIKAMWI nhamba. Unofanira kuwana nayo

In nekugadzirisa matambudziko maererano zvinoenderana anofanira kunzwisiswa nokutora vanoverengeka vanofarira. Pane nguva apo unofanira kutora mugove akasiyana variables. enzanisa:
