Whakaoti i te ((25div4)*30%)+((250div5)-4^2)=

$$((25 \div 4) \times 30 \% )+((250 \div 5)- { 4 }^{ 2 } )=$$

Ngā Upane Otinga

Whakahekea te hautanga \frac{30}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.

$$\frac{25}{4}\times \frac{3}{10}+\frac{250}{5}-4^{2}$$

Me whakarea te \frac{25}{4} ki te \frac{3}{10} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{25\times 3}{4\times 10}+\frac{250}{5}-4^{2}$$

Mahia ngā whakarea i roto i te hautanga \frac{25\times 3}{4\times 10}.

$$\frac{75}{40}+\frac{250}{5}-4^{2}$$

Whakahekea te hautanga \frac{75}{40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{15}{8}+\frac{250}{5}-4^{2}$$

Whakawehea te 250 ki te 5, kia riro ko 50.

$$\frac{15}{8}+50-4^{2}$$

Tātaihia te 4 mā te pū o 2, kia riro ko 16.

$$\frac{15}{8}+50-16$$

Tangohia te 16 i te 50, ka 34.

$$\frac{15}{8}+34$$

Me tahuri te 34 ki te hautau \frac{272}{8}.

$$\frac{15}{8}+\frac{272}{8}$$

Tā te mea he rite te tauraro o \frac{15}{8} me \frac{272}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{15+272}{8}$$

Tāpirihia te 15 ki te 272, ka 287.

$$\frac{287}{8}$$

Tauwehe

$$\frac{7 \cdot 41}{2 ^ {3}} = 35\frac{7}{8} = 35.875$$
