Aromātai

$$\frac{1}{4}=0.25$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 7 me 28 ko 28. Me tahuri \frac{5}{7} me \frac{3}{28} ki te hautau me te tautūnga 28.

$$\frac{\frac{20}{28}+\frac{3}{28}}{\frac{3\times 7+2}{7}}$$

Tā te mea he rite te tauraro o \frac{20}{28} me \frac{3}{28}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{\frac{20+3}{28}}{\frac{3\times 7+2}{7}}$$

Tāpirihia te 20 ki te 3, ka 23.

$$\frac{\frac{23}{28}}{\frac{3\times 7+2}{7}}$$

Whakareatia te 3 ki te 7, ka 21.

$$\frac{\frac{23}{28}}{\frac{21+2}{7}}$$

Tāpirihia te 21 ki te 2, ka 23.

$$\frac{\frac{23}{28}}{\frac{23}{7}}$$

Whakawehe \frac{23}{28} ki te \frac{23}{7} mā te whakarea \frac{23}{28} ki te tau huripoki o \frac{23}{7}.

$$\frac{23}{28}\times \frac{7}{23}$$

Me whakarea te \frac{23}{28} ki te \frac{7}{23} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{23\times 7}{28\times 23}$$

Me whakakore tahi te 23 i te taurunga me te tauraro.

$$\frac{7}{28}$$

Whakahekea te hautanga \frac{7}{28} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.

$$\frac{1}{4}$$

Tauwehe

$$\frac{1}{2 ^ {2}} = 0.25$$
