Kua tāruatia ki te papatopenga
\frac{3\times 4x}{15}-\frac{5x}{15}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o 5 me 3 ko 15. Whakareatia \frac{4x}{5} ki te \frac{3}{3}. Whakareatia \frac{x}{3} ki te \frac{5}{5}.
\frac{3\times 4x-5x}{15}
Tā te mea he rite te tauraro o \frac{3\times 4x}{15} me \frac{5x}{15}, me tango rāua mā te tango i ō raua taurunga.
\frac{12x-5x}{15}
Mahia ngā whakarea i roto o 3\times 4x-5x.
\frac{7x}{15}
Whakakotahitia ngā kupu rite i 12x-5x.
