\frac{5}{7}-\frac{2}{x}
Tuhia te 1\times \frac{2}{x} hei hautanga kotahi.
\frac{5x}{7x}-\frac{2\times 7}{7x}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o 7 me x ko 7x. Whakareatia \frac{5}{7} ki te \frac{x}{x}. Whakareatia \frac{2}{x} ki te \frac{7}{7}.
\frac{5x-2\times 7}{7x}
Tā te mea he rite te tauraro o \frac{5x}{7x} me \frac{2\times 7}{7x}, me tango rāua mā te tango i ō raua taurunga.
\frac{5x-14}{7x}
Mahia ngā whakarea i roto o 5x-2\times 7.
