Haeba u batla ho tseba hore na bolelele ba ho sokoloha ka likala tse fapaneng ke bofe, leka sena,sekala bolelele ho sokoloha sesebelisoa, e re thusa ho bala bolelele ka potlako.
Calculator ena e re thusa ho fumana tekanyo pakeng tsa bolelele ba bobeli, ho kenya bolelele ba bobeli feela, e tla lekanya tekanyo ea tekanyo, e ts'ehetsa li-unit tse fapaneng tsa bolelele (mm, cm, m, km, in, ft, yd, mi), ho phaella moo e lumellanang. setšoantšo sa pono le foromo, ho utloisisa mokhoa oa ho bala le sephetho habonolo.
Ka lipalo tse peli tse tšoanang tsa geometri, sekhahla sa sekhahla ke karo-karolelano ea mahlakore a bona a ts'oanang, ho arola bolelele ba mahlakore a mabeli ho tla fana ka karolelano, mohlala.
4 le 10 li aroloa ka 2
Bolelele A : 4 ÷ 2 = 2
Bolelele B : 10 ÷ 2 = 5
kahoo sekala ho tloha ho A ho ea ho B ke 2:5
12 le 3 li aroloa ka 3
12 ÷ 3 = 4
3 ÷ 3 = 1
12:3 karo-karolelano e nolofalitsoeng ke 4:1
kahoo sekala sa lisenthimithara tse 12 ho isa ho tse 3 ke 4:1
1⁄4 ho = 1 ÷ 4 = 0.25 in
2 ft = 12 × 2 = 24 in
1 ÷ 0.25 = 4
24 × 4 = 96
0.25:24 karo-karolelano e nolofalitsoeng ke 1:96
kahoo sekala sa lisenthimithara tse 1⁄4 ho isa maotong a 2 ke 1:96
