Whakaoti i te 53/10-38/15

$$5 \frac { 3 } { 10 } - 3 \frac { 8 } { 15 }$$

Aromātai

$$\frac{53}{30}\approx 1.766666667$$

Ngā Upane Otinga

Whakareatia te 5 ki te 10, ka 50.

$$\frac{50+3}{10}-\frac{3\times 15+8}{15}$$

Tāpirihia te 50 ki te 3, ka 53.

$$\frac{53}{10}-\frac{3\times 15+8}{15}$$

Whakareatia te 3 ki te 15, ka 45.

$$\frac{53}{10}-\frac{45+8}{15}$$

Tāpirihia te 45 ki te 8, ka 53.

$$\frac{53}{10}-\frac{53}{15}$$

Ko te maha noa iti rawa atu o 10 me 15 ko 30. Me tahuri \frac{53}{10} me \frac{53}{15} ki te hautau me te tautūnga 30.

$$\frac{159}{30}-\frac{106}{30}$$

Tā te mea he rite te tauraro o \frac{159}{30} me \frac{106}{30}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{159-106}{30}$$

Tangohia te 106 i te 159, ka 53.

$$\frac{53}{30}$$

Tauwehe

$$\frac{53}{2 \cdot 3 \cdot 5} = 1\frac{23}{30} = 1.7666666666666666$$
