Aromātai

$$\frac{14101}{60}\approx 235.016666667$$

Ngā Upane Otinga

Tāpirihia te 45.5 ki te 6.8, ka 52.3.

$$52.3\times 4.5-\frac{4}{12}$$

Whakareatia te 52.3 ki te 4.5, ka 235.35.

$$235.35-\frac{4}{12}$$

Whakahekea te hautanga \frac{4}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$235.35-\frac{1}{3}$$

Me tahuri ki tau ā-ira 235.35 ki te hautau \frac{23535}{100}. Whakahekea te hautanga \frac{23535}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{4707}{20}-\frac{1}{3}$$

Ko te maha noa iti rawa atu o 20 me 3 ko 60. Me tahuri \frac{4707}{20} me \frac{1}{3} ki te hautau me te tautūnga 60.

$$\frac{14121}{60}-\frac{20}{60}$$

Tā te mea he rite te tauraro o \frac{14121}{60} me \frac{20}{60}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{14121-20}{60}$$

Tangohia te 20 i te 14121, ka 14101.

$$\frac{14101}{60}$$

Tauwehe

$$\frac{59 \cdot 239}{3 \cdot 5 \cdot 2 ^ {2}} = 235\frac{1}{60} = 235.01666666666668$$
