Me pēhea te ki te Tātaihia te ōrau o

Mohio pehea ki te tātai i te ōrau o te tau e taea e whai hua e kore anake ki ngā ākonga kura nui. I roto i te ora rā, e hiahiatia ana tenei pūkenga i roto i te tikanga ki te tātai i te utu nama, tātai me te taki mēnā kua tātai koe te tāke kaute uara pono i runga i te taenga atu o te utu. A he maha nga kaimahi i te whānui o ngā kamupene me hinonga momo ko te kaha ki te tika e ki te mahi i runga i.

He aha te mea te reira - he ōrau? mahara ia hōtaka kura e i roto i te ao whakaaro te ōrau te ki kia kotahi-rau o tetahi wahi. Ko, i roto i te kupu atu, te kupu "3 ōrau" kia matau rite 3 haurau o tetahi tau. tuhituhi iwi mō te fuonounou whakaae ti'araa o te kupu "ōrau" tohu "%".

A i te kura e matau tatou katoa pehea ki te tātai i te ōrau o te tau: te tau wehea e kotahi rau, te kimi i te uara o tetahi ōrau, a ka nui haere te huawehe hua e te maha e tohu ana i te nui o te moni e hiahia ana koe ki te kitea.

Hei tauira, he mea e tika ana ki te mohio he aha te mea 28% o 500. kia te whakaaroaro ana e whai ake:

1. kitea tatou i te rahi o te 1% o te wehenga 500.

500: 100 = 5

1. kitea tatou he tau tomu'a whiwhi e whakanuia te huawehe e 100.

5 X 28 = 140.

Ko, 28% o te 500 - ko te 28/100 500. I roto i te ara tetahi, ka taea e koe te tuhi i tenei mahi:

500 x 28/100 = 140.

Na me pehea ki te tātai i te ōrau e kore ko o te tau tonu ngāwari i roto i to koutou ngakau, a kahore he wahi katoa he pene me te pepa ki te ringa, engari he tokomaha tenei ra whakamahi tātaitai.

Hoki te tātaitanga taea te whakamahi i te tikanga whakaahuatia ana i runga: he maha tomu'a o kotahi rau ka wehea e te nui e hiahiatia ana whakanuia ōrau.

He ko te pea o te tātai tere:

1. I roto i te tātaitai tomo te he maha tomu'a. I roto i to tatou take - 500.
2. press Panuku "tini".
3. Na ka waea te tokomaha o te moni e hiahiatia ana - no te to tatou kōwhiringa ko te 28.
4. Engari o te tohu taurite i runga i te tātaitai whiriwhiri%.
5. whiwhi tatou i te hua - he reira 140 i roto i tenei tauira.

A me pehea ki te tātai i te ōrau o te tau i runga i te rorohiko, mā te whakamahi i te mahi tātai i roto i te «Excel» hōtaka? Ko reira ano hoki he tukanga tika ohie.

1. I roto i te pūtau e whakaatu te ōrau tātai tohu rite tomo "=".
2. Next, he maha tomu'a o tuhia, i nei ki te titiro mo te ōrau "wāhitau" o te pūtau, te wahi e kua tomo te tau ranei. Tatou, i roto i to tatou hi'oraa, whakamōhio tatou te tau 500.
3. Ko te taahiraa toru ko ki haina te whakaingoatanga "tini" ranei "*".
4. Na kia tatou tuhi i te maha e tohu ana i te tokomaha o te moni e hiahiatia ana. Hoki tatou ko reira 28.
5. Ko te taahiraa penultimate ko te whakataki o te tohu "ōrau", i te mea o te puka "%".
6. Ki te tiki i te hua koutou pēhi anake te pātene i runga i te papapātuhi «E tomo». Ko te hua - 140 - e kore e waiho puhoi ki te puta i runga i te aroturuki.

I mua i te tīmata koe i te hōtaka "Excel" ki te kia pātene kiore mahue ki te hoatu i roto i te pūtau o te tepu te hōputu tika whakamahi i te "Tahua", ranei "Hōputu - Pūtau - Numbers - moni."

tauira Reflux o pehea ki te tātai i te ōrau o te tau, ko te kōwhiringa o te kimi e hia ōrau o tetahi tau e tetahi.

Hei tauira, e hoatu matou tau 140 me 500. Ko te pātai, ko te kupu: he aha te ōrau ko 140 500?

1. Tuatahi, kitea tatou nei kotahi ōrau ko 500. Ko, haere haere koroheke, me te wehenga i te ara iahiko 500 ki te whiwhi 100. 5.
2. Na to tatou ki te kitea i roto i te tini o ōrau kei roto i te maha tomu'a o 140. Ki te mahi i tenei, e hiahia ana koe ki te wehe 140 e 5. whiwhi tatou i te taua 28 ōrau!
3. Ka taea te tuhituhi kotahi tātai mō tenei tātai e whai ake:

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

E ko, te maha o 140 i te 500 ko 28 ōrau.

I roto i te tikanga ki te kitea i roto i te mea ōrau ko tetahi maha o tetahi, kia wehe matou te maha iti o atu tūmataiti, me te tini i te 100.

Enei pūkenga he kaipakihi tino nei e whai wāhi i roto i te hokohoko. A, no te te whakatakoto utu mō taonga te tikanga titau te kaha, me pehea ki te tātai i te ōrau o te tau, i te mea he te hiahia ki te "tinihanga" i runga i te hua mā te whakamahi i tenei mahi. Ko te ara tino watea ki te hanga i te whānuitanga katoa o te tinihanga taua rite te ōrau, hei tauira 15%.

Ko mo te tātai o te moni kupenga, me te tahi atu pūkenga e tika ana. Hei tauira, ko te moni o ia rā i roto i te turanga kau 3450 moni. He aha te te moni kupenga i taonga hokona? Ētahi kaipakihi tuhi hau'a, tātai 15% o te moni kerekere me te hapa kerekere! Te whakatahi i tohanga te ara kupu he "tinihanga", a ka noho ratou, me te rakuraku o ratou upoko, no hea reira ko te kaimahi.

A he tino māmā mea katoa. I muri i tākai kore te hua i tapae 100% o te utu, me te 100% + 15% = 115%. Na reira, ki te kitea te moni o nga moni uara tapiritia, tatau 15% te rite e whai ake nei:

1. kore He e 1% o te moni, wehewehe i te reira i te 100, a 115. Ko, i roto i tenei take,

3450: 115 = 20

1. Na inaianei e taea e koe te rapu mo te uara tapiritia e taea kia maia tango i te tohanga.

20 X 15 = 300

E tangohia ēnei whika "i te tuanui", na e kore e e nui e pā ana ki tenei raraunga. Ko te tikanga tātai ratou tika whakarongo, e kore ratou e whai hapa.
