Whakaoti i te 42/35-(211/35-2/35)

$$4 \frac { 2 } { 35 } - ( 2 \frac { 11 } { 35 } - \frac { 2 } { 35 } )$$

Aromātai

$$\frac{9}{5}=1.8$$

Ngā Upane Otinga

Whakareatia te 4 ki te 35, ka 140.

$$\frac{140+2}{35}-\left(\frac{2\times 35+11}{35}-\frac{2}{35}\right)$$

Tāpirihia te 140 ki te 2, ka 142.

$$\frac{142}{35}-\left(\frac{2\times 35+11}{35}-\frac{2}{35}\right)$$

Whakareatia te 2 ki te 35, ka 70.

$$\frac{142}{35}-\left(\frac{70+11}{35}-\frac{2}{35}\right)$$

Tāpirihia te 70 ki te 11, ka 81.

$$\frac{142}{35}-\left(\frac{81}{35}-\frac{2}{35}\right)$$

Tā te mea he rite te tauraro o \frac{81}{35} me \frac{2}{35}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{142}{35}-\frac{81-2}{35}$$

Tangohia te 2 i te 81, ka 79.

$$\frac{142}{35}-\frac{79}{35}$$

Tā te mea he rite te tauraro o \frac{142}{35} me \frac{79}{35}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{142-79}{35}$$

Tangohia te 79 i te 142, ka 63.

$$\frac{63}{35}$$

Whakahekea te hautanga \frac{63}{35} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.

$$\frac{9}{5}$$

Tauwehe

$$\frac{3 ^ {2}}{5} = 1\frac{4}{5} = 1.8$$
