Ngā Upane Otinga

Whakarohaina te \frac{2.8}{1.6} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{28}{16}\times \frac{2-\frac{1}{2}}{\frac{3\times 2+1}{2}}$$

Whakahekea te hautanga \frac{28}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{7}{4}\times \frac{2-\frac{1}{2}}{\frac{3\times 2+1}{2}}$$

Me tahuri te 2 ki te hautau \frac{4}{2}.

$$\frac{7}{4}\times \frac{\frac{4}{2}-\frac{1}{2}}{\frac{3\times 2+1}{2}}$$

Tā te mea he rite te tauraro o \frac{4}{2} me \frac{1}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{7}{4}\times \frac{\frac{4-1}{2}}{\frac{3\times 2+1}{2}}$$

Tangohia te 1 i te 4, ka 3.

$$\frac{7}{4}\times \frac{\frac{3}{2}}{\frac{3\times 2+1}{2}}$$

Whakareatia te 3 ki te 2, ka 6.

$$\frac{7}{4}\times \frac{\frac{3}{2}}{\frac{6+1}{2}}$$

Tāpirihia te 6 ki te 1, ka 7.

$$\frac{7}{4}\times \frac{\frac{3}{2}}{\frac{7}{2}}$$

Whakawehe \frac{3}{2} ki te \frac{7}{2} mā te whakarea \frac{3}{2} ki te tau huripoki o \frac{7}{2}.

$$\frac{7}{4}\times \frac{3}{2}\times \frac{2}{7}$$

Me whakarea te \frac{3}{2} ki te \frac{2}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{7}{4}\times \frac{3\times 2}{2\times 7}$$

Me whakakore tahi te 2 i te taurunga me te tauraro.

$$\frac{7}{4}\times \frac{3}{7}$$

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

$$\frac{7\times 3}{4\times 7}$$

Me whakakore tahi te 7 i te taurunga me te tauraro.

$$\frac{3}{4}$$

Tauwehe

$$\frac{3}{2 ^ {2}} = 0.75$$
