Whakaoti i te 152/5-63/5-63/4

$$15 \frac { 2 } { 5 } - 6 \frac { 3 } { 5 } - 6 \frac { 3 } { 4 }$$

Aromātai

$$\frac{41}{20}=2.05$$

Ngā Upane Otinga

Whakareatia te 15 ki te 5, ka 75.

$$\frac{75+2}{5}-\frac{6\times 5+3}{5}-\frac{6\times 4+3}{4}$$

Tāpirihia te 75 ki te 2, ka 77.

$$\frac{77}{5}-\frac{6\times 5+3}{5}-\frac{6\times 4+3}{4}$$

Whakareatia te 6 ki te 5, ka 30.

$$\frac{77}{5}-\frac{30+3}{5}-\frac{6\times 4+3}{4}$$

Tāpirihia te 30 ki te 3, ka 33.

$$\frac{77}{5}-\frac{33}{5}-\frac{6\times 4+3}{4}$$

Tā te mea he rite te tauraro o \frac{77}{5} me \frac{33}{5}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{77-33}{5}-\frac{6\times 4+3}{4}$$

Tangohia te 33 i te 77, ka 44.

$$\frac{44}{5}-\frac{6\times 4+3}{4}$$

Whakareatia te 6 ki te 4, ka 24.

$$\frac{44}{5}-\frac{24+3}{4}$$

Tāpirihia te 24 ki te 3, ka 27.

$$\frac{44}{5}-\frac{27}{4}$$

Ko te maha noa iti rawa atu o 5 me 4 ko 20. Me tahuri \frac{44}{5} me \frac{27}{4} ki te hautau me te tautūnga 20.

$$\frac{176}{20}-\frac{135}{20}$$

Tā te mea he rite te tauraro o \frac{176}{20} me \frac{135}{20}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{176-135}{20}$$

Tangohia te 135 i te 176, ka 41.

$$\frac{41}{20}$$

Tauwehe

$$\frac{41}{2 ^ {2} \cdot 5} = 2\frac{1}{20} = 2.05$$
