Isingeniso

Emhlabeni Kumathematika nezibalo, kuvamile ukuzwa amagama athi "isilinganiso" kanye "nokulinganisa." Nakuba womabili la magama ebhekisela ebudlelwaneni phakathi kwamanani amabili, awasho into efanayo. Kulesi sihloko, sizochaza umehluko phakathi kwamagama womabili kanye nendlela asetshenziswa ngayo kwizibalo.

Iyini isilinganiso?

Isilinganiso ubuhlobo phakathi kwamanani amabili engavezwa ngokwefraction noma inombolo yedesimali. Isibonelo, uma unama-apula angu-10 namapheya angu-5, isilinganiso sama-apula namapheya singaba ngu-2 kuya ku-1, noma 2/1. Kulokhu, inombolo 2 imele inombolo yama-apula futhi inombolo 1 imele inani lamapheya.

Iyini isilinganiso?

Ingxenye iwukuqhathanisa phakathi kobudlelwano obubili noma izilinganiso. Isibonelo, uma unesikhwama esinama-apula angu-8 namapheya angu-4, nesinye isikhwama esinama-apula angu-5 namapheya angu-3, ​​ungaqhathanisa isilinganiso sama-apula namapheya esikhwameni ngasinye ukuze unqume ukuthi ayalingana yini. Kulesi simo, isilinganiso sesikhwama sokuqala singu-2 kuya ku-1 (8/4), kuyilapho isilinganiso sesikhwama sesibili singu-1,67 kuya ku-1 (5/3). Njengoba izilinganiso azilingani, izikhwama azilingani.

Zisetshenziswa kanjani ezibalweni?

Izilinganiso nezilinganiso zisetshenziswa emagatsheni ahlukene ezibalo, njengejometri, izibalo kanye nezibalo. Ku-geometry, isibonelo, izilinganiso zisetshenziselwa ukukala ubukhulu bama-engeli nobukhulu bezinto. Ku-arithmetic, izilinganiso zisetshenziselwa ukubala izaphulelo, amaphesenti, namathiphu. Ezibalweni, zisetshenziselwa ukukala ubudlelwano phakathi kwezinto eziguquguqukayo nokubala izibalo ezifana ne-coefficient yokuxhumanisa.

Iziphetho

Sengiphetha, izilinganiso nezilinganiso zihlobene kodwa imiqondo yezibalo ehlukene. Isilinganiso simane siwubudlelwane phakathi kwamanani amabili, kuyilapho ingxenye iwukuqhathanisa phakathi kobudlelwane obubili noma izilinganiso. Womabili la magama asetshenziswa ezindaweni ezehlukene zezibalo futhi abalulekile ekuqondeni nasekuhlaziyeni ulwazi lwezinombolo ekuphileni kwansuku zonke.
