Ziyi-40 cm ubude?

Ziyi-40 cm ubude?

  • Yonke into ilula, ezi ziiyunithi eziqhelekileyo zemilinganiselo yenkqubo yeC. Idesimitha enye ineesentimitha ezilishumi. Kodwa ezi ayizizo iinwele ezisikelwe umlinganiselo. Ukuba ufuna ukwazi ukuba zingaphi iipesenti ezingama-40 eesentimitha ezilingana kwiidimitha, ke impendulo echanekileyo iyi-0,4 yeesikwere.

  • Khumbula iiyunithi zomlinganiselo wobude kunye nomyinge wazo:

    Kwisentimitha enye - iimilimitha ezilishumi, kwi-decimeter enye - 10 cm, njl.

    Amashumi amane eesentimitha ubude. Kodwa, kuba sifuna inani leesentimitha ezisikwere ngeesentimitha ezingama-40, ngoko iidimitha ezi-4 zisadinga ukwahlula-hlulwa nge-10. Sifumana i-0,4 cm ye -were.

    Ke, i-40 san-s ilingana no-0,4 yeesikwere.

  • Ukwenza uguqulelo olunje, kuya kufuneka sibhekise kumaxabiso asetafileni asekwe, ukuba Kukho iisentimitha ezilishumi kwidesimitha nganye, kodwa ngokubhekisele kuloo ndawo, ke

    1 dm iphindwe kabini = 100 cm ububanzi;

    Ngokuhambelana Iisentimitha ezingama-40 eziphindwe kabini = 0,4 yeesentimitha eziphindwe kabini.

  • Ukutshintshelwa komlinganiso kwisikwere uye kwesinye kusoloko kuba ngumsebenzi onzima kubantwana besikolo, kwaye ngenene kwabo balibale iziseko zabantu abadala. Ndiza kuzama ukwenza inkcazo eqondakalayo yobuchule bokuguqulela olo hlobo. Masithi sinesentimitha ezingama-40. Ukufumanisa ukuba zingaphi iidimitha zekwere ezi ekufuneka zibaliwe, zingaphi iisentimitha kwidesimitha enye. Iadimitha ziipesenti ezili-10. Isikwere sedreyitha sisikwere se-10x10 cm. Inezikwere ezili-100 zeesentimitha. Ngoku sizahlulahlula iisentimitha zethu ngenani labo kwidesimitha enye: 40/100 = 0.4. Ifumene impendulo: i-0.4 ye decimeter yesikwere.

    Ke ngoku, khomba ngomba, ngezenzo zethu:

    1 Khumbula ukuba zingaphi iisentimitha kwidesimitha (imitha, iikhilomitha, i millimitha kunye nezinye)

    2 Fumana ukuba zingaphi iisentimitha kwidesimitha enye

    3 Yahlula-hlula iisentimitha zethu ngeesentimitha ezi-skwele.

  • Ukusombulula ingxaki, khumbula iiyunithi: i-1 yeesentimitha - i-10 yeemilimitha, isi-1 sentimita - i-10 yeesentimitha.

    Kuya kuvela ukuba i-40 yeesentimitha ezi-4 zeesentimitha. Ukufumanisa ukuba zingaphi iidimitha eziwere, kufuneka wahlule nge-10.

    Ngokuhambelana, impendulo: zii-0,4 zeemitha eziimitha. iitrayimenti.

  • Imilinganiselo yobude kunye nendawo inokuguqulwa ukusuka kwiunithi yokutshintsha ukuya kwenye. Kufuneka nje ukwazi ukuba yintoni ehambelana noko.

    Iisentimitha kunye neerimitha zilinganisa ubude.

    1 dm = 10 cm.

    Ukuba ulinganisa indawo, ngoko iisentimitha, iidimitha, iimitha, njl. ziya kuphawulwa;

    Ukuba ufuna ukuguqula i-40 cm ephindwe kabini (40 cm2) ukuya kwiidimitha, sebenzisa umyinge:

    1 dm2 = 100 cm2

    Ke ngoko i-40 cm2 = 0.4 dm2

    Akunakwenzeka ukuguqula ubude (i-cm) kuphela endaweni (nge-cm okanye i-dm ephindwe kabini)!

  • Iisentimitha ezingama-40 ziidemitha ezi-4, kodwa hayi isikwere. Ngokucacileyo udideka iiyunithi zemilinganiselo yobude nendawo. Kwaye & quot; Abazenzisi besikwere; -Le nto iyothusa ngokubanzi!

    Kwidesimitha enye yeesentimitha

    Kwidesimitha enye ye-SQUARE ye-100 ye-SQUARE iisentimitha.

    Oko kukuthi, i-40 cm ngu-4 dm, kwaye i-40 cm ^ 2 ngu-0,4 dm ^ 2

  • Iisentimitha ezingama-40 ubude. Kodwa kuba kufuneka uguqule iisentimitha kungekuphela nje kwiidimitha, kodwa kwiisikwere, ke amashumi amane eesentimitha aya kuba ngokulingana ne-4 yeesentimitha. Yiyo kuphela, ingxaki isonjululwe.
