Las izahlulo zinokuvela zibe nzima kancinci ukusebenza kwezibalo xa sifunda; kodwa, inyani kukuba kubalulekile ukuba siyazi indlela yokwenza ngokuchanekileyo, kuba le misebenzi siyisebenzisa yonke imihla. Ke ngoko, apha siza kuchaza yonke into ekufuneka uyazi malunga nabo.

Yintoni ukwahlula? 

Phambi kokuba sifunde ukwahlulahlula, kufuneka sazi ukuba xa sithetha ngokwahlulahlula, asibhekiseli ekwahluleni izinto okanye izinto ezilinganayo.

  • Umzekelo: ukuba sinebhaskithi enama-apile alishumi (10), kwaye sifuna ukwahlulahlule kwiibhaskithi ezimbini (2) eziqulathe inani elifanayo lama-apile; Siwahlula njani ii-apile ?; Kulula kakhulu, sibeka ama-apile amahlanu (5) kwibhaskithi enye kunye nama-apile amahlanu kwenye, kungoko sinee-apile ezili-10 kwiibhaskithi ezi-2.

Icandelo lesahlulo 

Sele siyazi ukuba sithetha ntoni xa sithetha ngokwahlulahlula; Kodwa, ngoku kubalulekile ukuba siyazi into eyenziwa yi iinxalenye zesahlulo, Masibone:

  • Isahlulo: sisixa esiza kusaba; Ukuthatha umzekelo odlulileyo, le iya kuba ziiapile ezilishumi.
  • Divisor: ngoku sinomfanekiso esizahlulahlulahlulahlulahlulahlulayo; Ngamanye amagama, iinxalenye esiza kuzabahambisa kuzo izinto. Kule meko, ibiya kuba ziibhasikiti ezimbini.
  • Quotient: le yimveliso yolwahlulo; ukuba kumzekelo wama-apile kunye neebhasikithi, iyakuba ntlanu; Oko kukuthi, sibeka ii-apile ezintlanu kwingobozi enye, saza esinye safaka ama-apile amahlanu kwenye.
  • Phumla: kwezinye iimeko, kuyakubakho inani eligqithisileyo, isixa esingenakusahlulwa; eya kuba yeyokuphumla. Eli nani lingaba ngu-zero (0) okanye enye, kodwa kufuneka ihlale ingaphantsi kwesahluleli; kwimeko yethu, intsalela ayi-zero, kuba sikwazile ukuhambisa zonke ii-apile ngokwanelisayo.

Ulwahlulo lwenombolo enye

Kulungile, ngoku masibone indlela yokwahlulahlula; Siza kuqala ngokwahlula-hlula ngenani elinye kwisahlukanisi; Masibone inkqubo, sithatha i-125 ngo-5 njengomzekelo.

  1. Into yokuqala ekufuneka yenziwe kukwazi ukuba mangaphi amanani esahlulelweyo esiya kuwathatha ukwahlulahlulahluli; inani lokwahlula-hlula esilithathayo, kufuneka lihlale lilingana okanye inkulu kune ukwahlula. Ke ngoko, kumzekelo we-125, asizukuqala ukwahlula ngokuthatha u-1, kuba lento ingaphantsi ko-5; masithathe nenombolo elandelayo, esishiya nenani le-12.
  2. Into elandelayo esiza kuyenza kukujonga inani eliza kuthi, xa liphindaphindwe ngesahluli, liphumele kwisahlulo; Ukuba akukho, siza kuthatha esona siphumo siphantsi sisondeleyo kwisahlulo kwaye sibasuse. Kumzekelo wethu, siphinda-phinda u-5 x 2, onika u-10; ngokukhupha u-12 - 10, siya kuba no-2.
  3. Ngoku, siza kuthoba inani elilandelayo lokwahlulahlula, kwaye siza kwenza inyathelo langaphambili kwakhona. Ke, ukuba besike sahlala no-2 sathoba u-5, kuyakufuneka sijonge inani elizakuthi xa liphindaphindwe ngo-5 lisinike u-25; Kule meko ingaba ngu-5, ngoko ke 25 - 25 = 0; Ukusukela ukusebenza kwangaphambili kunike u-0, akusekho manani okwahlulahlulwa, ngoko ke sithi u-125 ÷ 5 = 25, kuba siqala ngokuphinda-phinda isi-5 ngesi-2 emva koko ngesi-5.

Amacandelo amabini namathathu 

Ukwahlulahlula ngamanani amabini anesithathu kwisahlukanisi kunokubonakala ngathi ngumsebenzi onzima ukuwenza; Kodwa inyani yeyokuba inkqubo iyakufana nakumahlulo enani elinye, kuphela siyakuthatha amanani amaninzi kwisahlulo njengoko kufunwa ngumhlukanisi; Masibone ngomzekelo:

  • Ukuba ufuna ukwahlula i-5738 ukuya kuma-73, kuya kufuneka uthathe ixabiso elilinganayo okanye elingaphezulu kwesahluli kwaye kule meko i-57 ingaphantsi kwama-73; masithathe ama-573 njengamanani okuqala.
  • Ngoku, sizakujonga inani xa liphindaphindwe ngo-73 lisinika u-573 okanye ngaphantsi, kulento iyakuba ngu7; emva koko 73 x 7 = 511, ngoko ke 573 - 511 = 62.
  • Into elandelayo esiza kuyenza kukuthoba inani u-8, ke siyakuba no-628- 73; ngoku siyayiphinda le nkqubo, sijonga ukuphinda-phinda kwama-73 angaphantsi okanye alingana no-628, anokuba ngu-8 kwaye sino-73 x 8 = 584; Ke sithathe 628 - 584 = 44.
  • Njengoko sibona, akusekho manani okunciphisa isahlulo; Ke sinama-78 ashiyekileyo ngenxa yokusebenza kwethu kwaye angama-44 aseleyo.

Ulwahlulo lwamaqhezu

Makhe siphakamise kancinci kwaye sifunde indlela yokwenza ulwahlulo lwamaqhezu; Akukho nto yoyikayo, ukuba uhoya ezi ndlela zimbini siza kukufundisa zona, uya kuyenza ngokuqhwanyaza kweliso; Masibone:

Phinda-phinda

Sisebenzisa le ndlela, siza kuthatha inani elingezantsi leqhezu lokuqala size siliphindaphinde ngedinomineyitha yesibini; esikushiyileyo, siza kukubeka njengenombolo. Emva koko, sizakuphindaphinda inani elilinganiswe ngokulinganayo kwinani lesibini; Isiphumo siya kuba sesingaphantsi kwaye senze lula iqhekeza elishiyekileyo. Masibone umzekelo:

izahlulo

  • Ukuba sino-4/8 ÷ 8/12, sizakuphindaphinda inani elingaphezulu kwelokuqala (4) ngumonyuli wecandelo lesibini (12); 4 x 12 = 48, Engahlala njengenani leqhezu lokugqibela.
  • Ngoku, kufuneka siphindaphinde inani elingaphezulu kwinxalenye yokuqala (8) ngenani elisecaleni lesibini (8); ishiya 8 x 8 = 64, idinomineyitha yeqhezu lokugqibela.
  • Iqhezu lethu liyakuhlala ngama-48/64; kodwa, kufuneka siyenze lula kangangoko kunokwenzeka, kwaye kule meko, imveliso yokugqibela iya kuba ngu-3/4.

Gcina kwaye wande 

Kulungile, kule meko into esiza kuyenza kukuthatha iqhezu lesibini kwaye silityale; okanye yintoni enye, sizakuthatha idinomineyitha kwaye siyiguqule kwinani, kwaye sibeke inani elingezantsi endaweni yedinomineyitha. Ngoku, siza kwenza lula naliphi na idinomineyitha ngayo nayiphi na inombolo kwaye siphindaphinde kwi-intanethi; masibone ngomzekelo:

  • Ukwahlula i-12/5 ukuya ku-6/4, into yokuqala esiyenzayo kukuguqula iqhezu lesibini, ukuze ibe ngu-4/6.
  • Emva koko, siqhubeka nokwenza lula amanani ngamanani; ukuba iinomboro zethu zezi: 12 = 2 x 2 x 3 kunye 4 = 2 x 2 kunye needinomineyitha zethu 5 = 5 kunye 6 = 2 x 3; kunokwenzeka ukuba kube lula ukubala ngenani kunye nedinomineyitha, kusishiya 2 x 2 x 2/5.
  • Ngoku, siza kwenza ukuphindaphinda kwi-intanethi kwe-2 x 2 x 2/5; Ukusuka kule nkqubo siza kuba no-8/5 njengeqhezu lokugqibela.

Siyathemba ukuba eli nqaku likuncede ukuba ufunde indlela yokwahlulahlula; Ngokunjalo, kuba khange siyichaze, apha sikushiya ividiyo apho bachaza indlela yokwahlulahlula ngamanani amathathu.

Sicebisa ukuba ungayishiyi ibhlog yethu ngaphandle kokubona inqaku lethu malunga nokuba zithini amanani endalo.
