Ngā Upane Otinga

Ko te maha noa iti rawa atu o 15 me 3 ko 15. Me tahuri \frac{8}{15} me \frac{2}{3} ki te hautau me te tautūnga 15.

$$\frac{8}{15}+\frac{10}{15}-\frac{3}{4}\times \frac{1}{71}$$

Tā te mea he rite te tauraro o \frac{8}{15} me \frac{10}{15}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{8+10}{15}-\frac{3}{4}\times \frac{1}{71}$$

Tāpirihia te 8 ki te 10, ka 18.

$$\frac{18}{15}-\frac{3}{4}\times \frac{1}{71}$$

Whakahekea te hautanga \frac{18}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{6}{5}-\frac{3}{4}\times \frac{1}{71}$$

Me whakarea te \frac{3}{4} ki te \frac{1}{71} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{6}{5}-\frac{3\times 1}{4\times 71}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 1}{4\times 71}.

$$\frac{6}{5}-\frac{3}{284}$$

Ko te maha noa iti rawa atu o 5 me 284 ko 1420. Me tahuri \frac{6}{5} me \frac{3}{284} ki te hautau me te tautūnga 1420.

$$\frac{1704}{1420}-\frac{15}{1420}$$

Tā te mea he rite te tauraro o \frac{1704}{1420} me \frac{15}{1420}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1704-15}{1420}$$

Tangohia te 15 i te 1704, ka 1689.

$$\frac{1689}{1420}$$

Tauwehe

$$\frac{3 \cdot 563}{2 ^ {2} \cdot 5 \cdot 71} = 1\frac{269}{1420} = 1.18943661971831$$
