Ngā Upane Otinga

Me tahuri te 120 ki te hautau \frac{240}{2}.

$$\frac{240}{2}+\frac{1}{2}-\frac{45.9}{4}$$

Tā te mea he rite te tauraro o \frac{240}{2} me \frac{1}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{240+1}{2}-\frac{45.9}{4}$$

Tāpirihia te 240 ki te 1, ka 241.

$$\frac{241}{2}-\frac{45.9}{4}$$

Whakarohaina te \frac{45.9}{4} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{241}{2}-\frac{459}{40}$$

Ko te maha noa iti rawa atu o 2 me 40 ko 40. Me tahuri \frac{241}{2} me \frac{459}{40} ki te hautau me te tautūnga 40.

$$\frac{4820}{40}-\frac{459}{40}$$

Tā te mea he rite te tauraro o \frac{4820}{40} me \frac{459}{40}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{4820-459}{40}$$

Tangohia te 459 i te 4820, ka 4361.

$$\frac{4361}{40}$$

Tauwehe

$$\frac{89 \cdot 7 ^ {2}}{5 \cdot 2 ^ {3}} = 109\frac{1}{40} = 109.025$$
