$$5 \frac { 1 } { 12 } - 3 \frac { 13 } { 18 }$$

Aromātai

$$\frac{49}{36}\approx 1.361111111$$

Ngā Upane Otinga

Whakareatia te 5 ki te 12, ka 60.

$$\frac{60+1}{12}-\frac{3\times 18+13}{18}$$

Tāpirihia te 60 ki te 1, ka 61.

$$\frac{61}{12}-\frac{3\times 18+13}{18}$$

Whakareatia te 3 ki te 18, ka 54.

$$\frac{61}{12}-\frac{54+13}{18}$$

Tāpirihia te 54 ki te 13, ka 67.

$$\frac{61}{12}-\frac{67}{18}$$

Ko te maha noa iti rawa atu o 12 me 18 ko 36. Me tahuri \frac{61}{12} me \frac{67}{18} ki te hautau me te tautūnga 36.

$$\frac{183}{36}-\frac{134}{36}$$

Tā te mea he rite te tauraro o \frac{183}{36} me \frac{134}{36}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{183-134}{36}$$

Tangohia te 134 i te 183, ka 49.

$$\frac{49}{36}$$

Tauwehe

$$\frac{7 ^ {2}}{2 ^ {2} \cdot 3 ^ {2}} = 1\frac{13}{36} = 1.3611111111111112$$
