Whakareatia te 10 ki te 7, ka 70.

$$70+\frac{22}{7}\times \frac{7}{2}\times \frac{7}{2}\times \frac{1}{2}$$

Me whakarea te \frac{22}{7} ki te \frac{7}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$70+\frac{22\times 7}{7\times 2}\times \frac{7}{2}\times \frac{1}{2}$$

Me whakakore tahi te 7 i te taurunga me te tauraro.

$$70+\frac{22}{2}\times \frac{7}{2}\times \frac{1}{2}$$

Whakawehea te 22 ki te 2, kia riro ko 11.

$$70+11\times \frac{7}{2}\times \frac{1}{2}$$

Tuhia te 11\times \frac{7}{2} hei hautanga kotahi.

$$70+\frac{11\times 7}{2}\times \frac{1}{2}$$

Whakareatia te 11 ki te 7, ka 77.

$$70+\frac{77}{2}\times \frac{1}{2}$$

Me whakarea te \frac{77}{2} ki te \frac{1}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$70+\frac{77\times 1}{2\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{77\times 1}{2\times 2}.

$$70+\frac{77}{4}$$

Me tahuri te 70 ki te hautau \frac{280}{4}.

$$\frac{280}{4}+\frac{77}{4}$$

Tā te mea he rite te tauraro o \frac{280}{4} me \frac{77}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{280+77}{4}$$

Tāpirihia te 280 ki te 77, ka 357.

$$\frac{357}{4}$$

Tauwehe

$$\frac{3 \cdot 7 \cdot 17}{2 ^ {2}} = 89\frac{1}{4} = 89.25$$
