$$30 - ( 1 - 5 \frac { 8 } { 10 } ) + 16$$

Aromātai

$$\frac{254}{5}=50.8$$

Ngā Upane Otinga

Whakareatia te 5 ki te 10, ka 50.

$$30-\left(1-\frac{50+8}{10}\right)+16$$

Tāpirihia te 50 ki te 8, ka 58.

$$30-\left(1-\frac{58}{10}\right)+16$$

Whakahekea te hautanga \frac{58}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$30-\left(1-\frac{29}{5}\right)+16$$

Me tahuri te 1 ki te hautau \frac{5}{5}.

$$30-\left(\frac{5}{5}-\frac{29}{5}\right)+16$$

Tā te mea he rite te tauraro o \frac{5}{5} me \frac{29}{5}, me tango rāua mā te tango i ō raua taurunga.

$$30-\frac{5-29}{5}+16$$

Tangohia te 29 i te 5, ka -24.

$$30-\left(-\frac{24}{5}\right)+16$$

Ko te tauaro o -\frac{24}{5} ko \frac{24}{5}.

$$30+\frac{24}{5}+16$$

Me tahuri te 30 ki te hautau \frac{150}{5}.

$$\frac{150}{5}+\frac{24}{5}+16$$

Tā te mea he rite te tauraro o \frac{150}{5} me \frac{24}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{150+24}{5}+16$$

Tāpirihia te 150 ki te 24, ka 174.

$$\frac{174}{5}+16$$

Me tahuri te 16 ki te hautau \frac{80}{5}.

$$\frac{174}{5}+\frac{80}{5}$$

Tā te mea he rite te tauraro o \frac{174}{5} me \frac{80}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{174+80}{5}$$

Tāpirihia te 174 ki te 80, ka 254.

$$\frac{254}{5}$$

Tauwehe

$$\frac{2 \cdot 127}{5} = 50\frac{4}{5} = 50.8$$
