Muchidzidzo Masvomhu, shoko rokuti Rupande (fraction in English) rinoreva chikamu kubva pane chinhu mhumburu. Rupande kana rwanyorwa rwunotaura kuti pari kuhwerengedzwa zvikamu zvakaenzana zvingani. Sokuti mapande matatu emana (3/4), Rupande rumwe rwemaviri (1/2), mapande mana emasere (4/7). Pakunyora kwakapfupiswa tichati 4/7 inonyorwa ichingonzi mana-pausere.
Rupande njee rwakafanana nekuti 1/2, 8/5, 4/7 chakaumbwa chiine nhamba izere pamusoro nenhamba izere pasi. Nhamba yepamusoro inonzi mberengi, iyi nhamba ndiyo inotaura kuti pane zvikamu zvingani zvakaenzana. Nhamba yepasi inonzi chirevazita, iyi nhamba inotaura kuti chinhu chizere (mhumburu) chakaumbwa nezvikamu zvakaenzana zvingani.
Rupande njee nemhando dzacho
Rupande njee inhamba yakanyorwa sezvinoti a/b. Apa a na b dzinenge dziri nhamba dzizere; a anonzi mberengi, b anonzi chirevazita. Mberengi inotaura kuti pane zvikamu zvakaenzanz zvingani. chirevazita chinotiudza kuti pane zvikamu zvingani zvakaenzana zvinoumba chizere chose uye hachifanirwe kuva zero. Pamuenzaniso 7/3 uye 5/9, mutsetse uri pakati penhamba mbiri unonzi mutsetse weRupande - fractional line.
Rupande njee chine mhando mbiri dzinoti Rupande rwakafanira uye Rupande rusakafanira.
Rupande rwakavhengana chinowanikwa panowedzaniswa nhamba izere neRupande rwakafanira; apa nhamba izere inenge isiri zero. Somuenzaniso kana kuchitaurwa makeke maviri pamwe nehafu yekeke inonyorwa ichinzi .
Rupande rwakavhengana imwe nzira yokunyora nhamba mhumburu ichiwedzaniswa neRupande rwakafanira. Rupande rwakavhengana runokwanisa kushandurwa kuva Rupande rusakafanira nenzira inotevera:
1. Nyora Rupande rwakavhengana sesvomhu; sokuti yoshandurwa kuva .
2. Shandura nhamba izere ive Rupande rusakafanira ruine chirevazita chakaenzana nedivi rine Rupande rwakafanira, .
3. Wedzanisa mapande maviri aya. Hwerengedzo inowanikwa ipapa inenge iri Rupande rusakafanira. Pamuenzaniso wapiwa, .
Zvinogonanwo kuti Rupande rusakafanira rushandurwe kuva Rupande rwakavhengana nenzira inotevera:
1. Gova mberengi nechirevazita. Pamusenzaniso uri pano, , gova 11 na 4. 11 ÷ 4 = 2 uye pane musarirwa 3.
2. Mungani (pasina musarirwa) ndiyo nhamba inotaridza divi rine nhamba izere paRupande rwakavhengana. Musarirwa ndiwo unova mberengi padivi rine Rupande rwakafanira. Pamuenzaniso wedu, 2 ndiye nhamba izere, 3 ndiye mberengi padivi rine Rupande rwakafanira.
3. chirevazita chitsva chakaenzana nechirevazita cheRupande rusakafanira. Pamuenzaniso chirevazita ndi 4. Saka .
Rupande rwakavhengana runogona kuva nhamba yakademera (negative number in English), sezvizvi , zvichibva zvaenzana sezvizvi .
