Ngā Upane mō te Whakaoti Whārite Rārangi

Whakahekea te hautanga \frac{9}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$x\times \frac{7}{8}=\frac{3}{4}$$

Me whakarea ngā taha e rua ki te \frac{8}{7}, te tau utu o \frac{7}{8}.

$$x=\frac{3}{4}\times \frac{8}{7}$$

Me whakarea te \frac{3}{4} ki te \frac{8}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x=\frac{3\times 8}{4\times 7}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 8}{4\times 7}.

$$x=\frac{24}{28}$$

Whakahekea te hautanga \frac{24}{28} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$x=\frac{6}{7}$$
