Ngā Upane Otinga

Whakawehe 5 ki te \frac{19}{16} mā te whakarea 5 ki te tau huripoki o \frac{19}{16}.

$$5\times \frac{16}{19}\times 3-\frac{1}{3}$$

Tuhia te 5\times \frac{16}{19} hei hautanga kotahi.

$$\frac{5\times 16}{19}\times 3-\frac{1}{3}$$

Whakareatia te 5 ki te 16, ka 80.

$$\frac{80}{19}\times 3-\frac{1}{3}$$

Tuhia te \frac{80}{19}\times 3 hei hautanga kotahi.

$$\frac{80\times 3}{19}-\frac{1}{3}$$

Whakareatia te 80 ki te 3, ka 240.

$$\frac{240}{19}-\frac{1}{3}$$

Ko te maha noa iti rawa atu o 19 me 3 ko 57. Me tahuri \frac{240}{19} me \frac{1}{3} ki te hautau me te tautūnga 57.

$$\frac{720}{57}-\frac{19}{57}$$

Tā te mea he rite te tauraro o \frac{720}{57} me \frac{19}{57}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{720-19}{57}$$

Tangohia te 19 i te 720, ka 701.

$$\frac{701}{57}$$

Tauwehe

$$\frac{701}{3 \cdot 19} = 12\frac{17}{57} = 12.298245614035087$$
