Njira zingapo kuwerengera kuchuluka kwa chiwerengero (ndi mtundu wofanana wa ntchito)

Mawerengedwe a kuchuluka kwa chiwerengero - mmodzi wa amenyana kuti zonse zizichitika mu sukulu pa maphunziro masamu. Koma izi sizikutanthauza kuti zonse kuchidziwa mosavuta. Ndipotu, mfundo ndi losavuta, chinthu chachikulu - kudziwa njira kutsimikiziridwa wa mawerengedwe pa mbali ya lonse ndi chidwi lonse.

1% - gawo zana la lonse, kotero kuti podziwa mtengo uwu mosavuta kuwerengera phindu gawo. Mwachitsanzo, 15% 60 kuchita masamu motere: kutenga 60 peresenti 100. Ndiye 1% - ndi 60/100 - 0,6. 15%, motero, zimapanga - 0.6 * 15 = 9. Izi ndi njira yoyamba kuwerengera kuchuluka kwa chiwerengero.

Njira yachiwiri - kufika mchimake. 15 zikugwirizanirana ndi 100 anafotokoza kuti X 60, ndiye 15/100 = × / 60. Kuthetsa chiwerengero wapangidwa m'njira ziwiri:

1. Sinthani kuti kumasonyeza × = 15 * 60/100. Kachiwiri, likukhalira: × = 9.
2. Pangani kutembenuka wina mu masitepe 2: 100x = 15 * 60, ndiko anapangira chulukanani crosswise. Kuyambira mawu amenewa, timachotsa zotsatirazi: 100X = 900. Choncho, × = 9.

Ngati muli ndi kulingalira kuchuluka zimene chiwerengero cha nambala ina, njira ndi zophweka kwambiri. Mwachitsanzo chiwerengero 70 ndi 13. Tiyeni 70 - 100% ndipo 13 - x. Ndiye 13/70 = × / 100. Kuthetsa chiwerengero angakhale njira kale bwino.

70 13 = 100; 70s = 1300; Ngati adzakhale ndi malo chachiwiri decimal, likukhalira kuti × = 18,57%.

Ngati inu mukudziwa kuchuluka wina wa chiwerengero ndi ayenera kupeza angapo, ndipo vutoli zingathe kuthetsedwa kwathunthu.

Mwachitsanzo, 16% - ndi 32. ndi inteja chiyani? Kachiwiri kulemba chiwerengero: 16% chikugwirizana ndi 100%, komanso 32 x. 16/100 = 32 / ×; 16X = 3200; × = 3200/16 = 200.

Ngati chikhalidwe ndi vuto kuti chiwerengero cha A ndi kuchuluka ena chiwerengero cha B, chimene chili chofunika kuwerengera ntchito chilinganizo lina lophweka. A / B * 100% - ichi adzakhala yankho. Mwachitsanzo, muyenera kupeza kuchuluka kwa chiwerengero 87 ndi nambala 329.

Kuwerengetsa chifukwa cha kachitidwe, timapeza 87/329 * 100% = 26,44%. Ngati njira iyiwalika pa nthawi yoyenera, kuthandiza adzabweranso kufanana: 87 amatanthauza 329, ngati × amatanthauza 100%, kuti ndi 87/329 = × / 100. Akatembenuka chiwerengero ichi, ife tikufika 329h = 87 * 100; 329h = 8700; × = 8700/329 = 26,44%.

Chabwino, kuipa losavuta pafupifupi onse pa khutu, ndipo mutu wanga: limodzi mwa magawo asanu - ndi 20%, chimodzi pa zinthu khumi - 10%, theka ndi kotala - 50% 25% motero. Kwa ena, ndi maganizo yabwino ndi bwino zambiri, ndipo wina ali ndi mosavuta ntchito peresenti. Kusiyana kwakukulu pakati kachiwiri ndi 50% satero.

Ndi Chiwerengero ndi kuchita idzakhala yophweka, chifukwa pali ngakhale batani wapadera kuti amalola kuti kuwerengetsa chidwi.

Ndithudi, zonse ntchito izi - Kupeza chiphunzitso chabe. Koma kuwerengera kuchuluka kwa chiwerengero angafunike mu moyo. Akugulitsa kuti aone 30% kuchotsera kumvetsa pa chinthu, kapena ndi kuchuluka ting'onoting'ono. Mukhoza kupeza chimene chinali mtengo sasamala, komanso recheck ogulitsa - chifukwa kawirikawiri ndi ogula sasamala ndi mfundo chidutswa cha mtengo wa kanjedza wokongola kwambiri.

Kuwerengetsa kuchuluka kwa chiwerengero ukafunidwe, ndi mawerengedwe a misonkho, ndithudi, amene amaona zinthu zoterozo. Ndipo, ndithudi, chidwi mawerengedwe mowirikiza anakumana zachuma, chuma, stockbrokers ndi ofufuza. Ndipotu, ngakhale mkazi wapakhomo zonse kuthana ndi chidwi, popanda kuzindikira n'komwe.

Mwachidule, mfundo ndi losavuta, ngakhale yovuta kwambiri pa koyamba. Komabe, pankhani kumvetsa, ntchito zokhudza mawerengedwe chidwi pa chiwerengero ndi pa gawo lonse, ngati mbewu. Inu basi kulemba ndi mkate pang'ono.
