Ngā Upane Otinga

Whakareatia te 38 ki te 125, ka 4750. Whakareatia te 125 ki te 27, ka 3375.

$$4750+\frac{15}{\frac{80}{100}}+3375$$

Whakawehe 15 ki te \frac{80}{100} mā te whakarea 15 ki te tau huripoki o \frac{80}{100}.

$$4750+\frac{15\times 100}{80}+3375$$

Whakareatia te 15 ki te 100, ka 1500.

$$4750+\frac{1500}{80}+3375$$

Whakahekea te hautanga \frac{1500}{80} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$4750+\frac{75}{4}+3375$$

Me tahuri te 4750 ki te hautau \frac{19000}{4}.

$$\frac{19000}{4}+\frac{75}{4}+3375$$

Tā te mea he rite te tauraro o \frac{19000}{4} me \frac{75}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{19000+75}{4}+3375$$

Tāpirihia te 19000 ki te 75, ka 19075.

$$\frac{19075}{4}+3375$$

Me tahuri te 3375 ki te hautau \frac{13500}{4}.

$$\frac{19075}{4}+\frac{13500}{4}$$

Tā te mea he rite te tauraro o \frac{19075}{4} me \frac{13500}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{19075+13500}{4}$$

Tāpirihia te 19075 ki te 13500, ka 32575.

$$\frac{32575}{4}$$

Tauwehe

$$\frac{5 ^ {2} \cdot 1303}{2 ^ {2}} = 8143\frac{3}{4} = 8143.75$$
