Momwe mungamasulire maminiti mu maola ndi mosiyana: zitsanzo, njira, nthawi zosangalatsa

Tiyeni tiyang'ane momwe tingatembenuzire maminiti mu maola ndi mosiyana. Choyamba, timavomereza kuti chidziwitso cha masamu chidzafunikila. Pambuyo pake, simungathe kuchita popanda kuwerengera apa. Ngati simukuzichita m'maganizo mwanu kapena papepala, ndiye gwiritsani ntchito calculator. Pansipa mudzapeza pafupifupi zonse zomwe mungasankhe kuti mutembenuzire maminiti maola.

Kuyambira kalelo mpaka lero

Yang'anani pa kujambula. Lili ndi magawo 60, omwe ndi masekondi 60 (mphindi). Amene ali mabwenzi ndi masamu, kwa nthawi yaitali adazindikira kuti sayansiyi ili ngati cholinga, zongopeka, motero zimakondweretsa. Anthu akale analibenso nzeru kuposa anthu a m'nthawi yathu ino, m'malo mwake, iwo anapindula ndi chinachake.

Tili ndi chiyani lero:

• Ola limodzi ndi mphindi 60;
• Mphindi imodzi ikufanana masekondi 60;
• Ola limodzi liri ndi masekondi 3600.

Inde, masekondi 3600 anapezeka pochulukitsa 60 minutes * masekondi 60. Tiyeni tiyang'ane mojambula: Mwachitsanzo, ora (fufuzani) ndi 12, ndi miniti (motalika) - amasonyeza kuti tsopano mphindi 20. Icho ndi maminiti makumi awiri a oyamba. Tsopano ganizirani momwe mungatembenuzire maminiti mu maora ndi chitsanzo ichi.

Mawerengedwe ophweka ndi ovuta mpaka ora limodzi

Kumbukirani chiwerengero cha sukulu ya pulayimale ndi kalasi 5: panali zidutswa. Kodi tikufika pati? Ola limodzi = 60 min. Ndipo tili ndi mphindi 20 zokha. Zingakhale zolakwika kuzindikira kuti maola 20/60 okha adutsa. Koma tikudziwa kuti tizigawo ting'onoting'ono tingachepetse. Tiyeni tichite izi:

20/60 = 1/3.

Chiwerengero chinadutsa 1/3 maola kapena, ngati tigawani, ndiye 0.33.

Lingalirani njira ina: kodi kotala la ola limatanthauza chiyani? Kodi ndimasintha bwanji mphindi ndi maola?

Maola 1/4 = Mphindi 15. Kodi izi zinachitika bwanji?

Mphindi 15/60 min. = 1/4.

Kodi mungalembe bwanji maminiti 10 patsiku? Njira yothetsera vutoli ndi yopanda pake:

10 min./60 min. = 1/6 ola = 0.167 maola. Mwachiwonekere, mbiri imeneyi si yolondola, choncho ndibwino kuti musamasulire maminiti khumi.

Oposa ola limodzi

Ambiri a ife tawonapo, monga, mwachitsanzo, zolembedwa mu ndondomeko ya filimuyo nthawi yake: 150 min. Momwe mungasinthire maminiti kwa maola awa? Dziwani kuti sipadzakhalanso magawo ena. Chifukwa chiyani? Chifukwa mu gawo lapitalo, panali nthawi yomwe inatha kupitirira ora limodzi. Ndipo tsopano, mosiyana, chirichonse. Zidzakhala zosavuta kuyang'ana pa dzanja limodzi, koma ndizovuta kwambiri.

Kotero, kubwerera ku 150 minutes. Kuti tisaganize motalika, tiyeni talingalira mwachidule mphindi 60 mpaka tifike kulakalaka 150: 60 min. + 60 min. = 120. Tiyenera kuyimitsa, chifukwa ngati muwonjezerapo mphindi 60, padzakhala 180, ndipo timakhala ndi mafilimu 150 okha. Timabwerera ku mphindi 120 zathu. Inde, awa ndi maola awiri. Ndipo tsopano kuchokera mphindi 150 tidzasiya 120. Zidzakhala 30.

Inu mukhoza kuchita izo mosiyana. Imani kwa mphindi 120 ndikuganiza mwakuya ndi theka la ora. Nazi zotsatira zanu: 150 min. = 2 maola 30 mphindi. = Maola 2.5.

Ndipo momwe mungapezere kuchokera maola 1.5 mphindi? Nthawi yomweyo perekani 1 ora mphindi 30: 60 + 30 = 90 minutes.

Njira ina: gawo la masamu ndilolimita limodzi ndi magawo khumi a magawo khumi, omwe atatha kusintha amasintha mawonekedwe: 15/10 = 3/2. Ndipotu, maola 1.5 ndi maola 3/2.

Tangoganizani phunziro pa grade 3, lomwe likukhudzana ndi tizigawo ting'onoting'ono. Panalinso zithunzi zojambulidwa zomwe zikuwonetsa zomwe 5/6 kapena 1/2 zikutanthauza.

N'chifukwa chiyani zofunikira zoterezi zimafunika?

Tangoganizani kuti mukuphunzira nthawi ya sitima zamagetsi. Kawirikawiri, lembani, mwachitsanzo, nthawi yoyendayenda: 1 ora mphindi zisanu. Zikuwoneka kuti chirichonse chikuwonekera. Koma tiyeni tiyerekeze kuti izi ziri maminiti angati? Mphindi 65. Zina: 2 hours 35 Mphindi? Tiyeni tiwerenge:

Maola 2 = Mphindi 120, onjezani maminiti 35. Zotsatira zake: 120 + 35 = 155 minutes.

Kotero ife tinayang'ana momwe tingamasulire maminiti mu maora ndi mosiyana. Kuti athe kuwerengera mwamsanga, ndi zofunika kudziwa zofunikira za masamu. Ngati simukupeza malingaliro, muyenera kuthetsa vuto pamapepala.
