Nhamba dzeDecimal neFractional
Nhamba dzedecimal nedzefractional inzira mbiri dzinowanzoshandiswa kumiririra fractions kana rational numbers. Dzese dzinoshanda basa rimwe chete, asi matauriro adzo uye mashandisirwo adzo akasiyana zvishoma. Chinyorwa chino chichatsanangura zvakadzama pfungwa dzese dziri mbiri uye mashandisirwo adzo muhupenyu hwezuva nezuva.
Nhamba dzeDecimal
Decimal isystem yenhamba yebase-ten inoshandisa decimal point kupatsanura nhamba dzese kubva kuzvikamu. Manhamba ari kuruboshwe rwedecimal point ndiwo chikamu chose chenhamba, nepo manhamba ari kurudyi rwedecimal point ari chikamu. Semuenzaniso, munhamba 45.67, 45 chikamu chose, uye 67 chikamu chezvikamu, chinova 67/100, kana 67 muzana.
Madecimals anoshandiswa zvakanyanya muhupenyu hwezuva nezuva, kunyanya mune zvemari, sainzi, uye mainjiniya. Semuenzaniso, mari inowanzo nyorwa muchimiro chedesimali. Kana mumwe munhu akatenga chimwe chinhu nemadhora mashanu nemakumi manomwe nemashanu, zvinoreva kuti madhora mashanu idhora rese, uye madhora mashanu idhora rimwe chete.
Kunyora kweDesimali
Kunyora nhamba dzedesimali kunotevera mitemo yakati:
1. Decimal Point: Decimal point inoshandiswa kupatsanura integer part kubva ku fractional part.
2. Mazero: Mazero anoiswa kuruboshwe rwedesimali kana nhamba yechikamu iri pasi peimwe, semuenzaniso, 0.25.
3. Kutenderera: Manhamba edesimali anowanzo tenderera kusvika kune nhamba yakati yenzvimbo dzedesimali mune mamwe mamiriro akadai semashoko emari.
Kushandura Nhamba Dzechikamu kuita Madecimals
Kushandura kubva panhamba diki kuenda panhamba diki kunogona kuitwa nekukamura nhamba nedhinominator. Semuenzaniso, kuti tishandure 1/2 kuita nhamba diki, tinoita kupatsanura kuri nyore: 1 ÷ 2 = 0.5.
Nhamba dzeChikamu
Nhamba dzezvikamu, kana kuti zvikamu sezvadzinowanzodaidzwa, ndeimwe nzira yekuratidza nhamba dzakarongeka. Chikamu chinonyorwa muchimiro che a/b, apo 'a' iri numerator, inoratidza kuti tine zvikamu zvingani, uye 'b' iri denominator, inoratidza kuti ingani zvikamu zvinodiwa kuti pave nechinhu chakazara.
Kunyora Zvidimbu
Kunyora nhamba dzezvikamu kunotevera mitemo chaiyo:
1. Nhamba neChinongedzo: Nhamba iri pamusoro pemutsetse wezvikamu, uye dhinomineta iri pasi payo. Semuenzaniso, mu3/4, 3 ndiyo nhamba, uye 4 ndiyo nhamba.
2. Zviri nyore: Zvidimbu zvinowanzo nyore kuti zvive nyore kunzwisisa. Semuenzaniso, 4/8 inogona kurerutswa kuita 1/2.
3. Zvidimbu Zvakasanganiswa: Kana nhamba yakakura kupfuura dhinominator, tinogona kuinyora senhamba yakasanganiswa. Semuenzaniso, 7/4 inogona kunyorwa se1 3/4.
Kushandura Madecimals kuita Manhamba Ezvikamu
Kushandura kubva panhamba yedesimali kuenda kunhamba yechikamu kunoitwa nekuona poindi yedesimali uye kuita kuti ive nyore. Semuenzaniso, 0.75 inogona kunyorwa se75/100, iyo inogona kurerutswa kuita 3/4.
Kuenzanisa kweDecimals neFractions
Masisitimu ese ari maviri ane zvakanakira nezvakaipira, pamwe nemashandisirwo azvo zvichienderana nemamiriro ezvinhu akati wandei.
1. Zviri Nyore Kushandisa: Madecimals ari nyore kushandisa pakuenzanisa uye pakuenzanisa nekuti ari nyore kuronga nekuenzanisa.
2. Kururama: Zvidimbu zvinowanzova zvakarurama pakumiririra. Chidimbu chakaita se1/3 chakarurama kupfuura nhamba yedesimali 0.333… iyo yakatenderedzwa.
3. Zviri nyore kana kuti zvakaoma: Zvidimbu zvinowanzova nyore muchimiro chazvo chakareruka, nepo nhamba dzedesimali dzichigona kuva dzakareba uye dzakaoma.
Mashandisirwo muHupenyu hweZuva Nezuva
1. Masvomhu neDzidzo: Zvidimbu zvinowanzo dzidziswa pakutanga kwechikoro chepuraimari kuti tinzwisise pfungwa dzehuwandu, zvikamu zvechinhu chose, uye chiyero.
2. Mari nehupfumi: Madecimals anowanzo shandiswa mukutengeserana kwemari kumiririra mitengo, mitengo yemubereko, uye midziyo.
3. Sainzi neUinjiniya: Pfungwa dzese dziri mbiri dzinoshandiswa mumhando dzakasiyana-siyana dzemashandisirwo, kubva pakuyera zviri nyore kusvika pakushandura mayuniti akaomarara.
Kuverenga kweDecimal neFractional
Mabasa ekutanga emasvomhu akadai sekuwedzera, kubvisa, kuwanza, uye kupatsanura anogona kuitwa ne decimals ne fractions.
1. Kuwedzera nekubvisa: Muzvikamu, tinoda denominator imwechete yekuwedzera nekubvisa. Zvisinei, muzvikamu zvemadesimali, tinongoda kurongedza madesimali.
Misal:
– 1/4 + 1/2 = 1/4 + 2/4 = 3/4
– 0.25 + 0.5 = 0.75
2. Kuwanza neKupatsanura: Kuwanza kwezvikamu nezvikamu zvemadesimali kuri nyore. Semuenzaniso, 0.5 0.4 = 0.2, uye 1/2 1/4 = 1/8.
Ukama neNhamba Dzepfungwa
Zvese madesimali nezvikamu zvidiki imhando dzenhamba dzakarongeka, kureva kuti, nhamba dzinogona kuratidzwa sekupatsanurwa kwenhamba mbiri dzakazara. Madesimali anodzokororwa kana anodzokororwa, akadai se0.333…, anogonawo kuratidzwa sezvikamu zvidiki, mune iyi nyaya 1/3.
Mhedziso
Kunzwisisa madesimali nema fractions hunyanzvi hwakakosha mumasvomhu nehupenyu hwezuva nezuva. Ose anopa nzira dzakasiyana asi dzinoenderana dzekumiririra nhamba dzakarongeka. Madesimali anorerutsa kuverenga kwakasiyana-siyana nekuenzanisa munyika yanhasi, nepo ma fractions achipa mifananiso inowanzova yakarurama uye iri nyore. Kugona ese ari maviri kuchatipa hunyanzvi hwakakura hwekuverenga uye hunyanzvi hwekuverenga kuti tikwanise kubata mamiriro akasiyana-siyana, kungave mudzidzo, mari, sainzi, kana mainjiniya.
