Whakaoti i te 5*5-4/9div8+28

$$5 \cdot 5- \frac{ 4 }{ 9 } \div 8+28$$

Aromātai

$$\frac{953}{18}\approx 52.944444444$$

Ngā Upane Otinga

Whakareatia te 5 ki te 5, ka 25.

$$25-\frac{\frac{4}{9}}{8}+28$$

Tuhia te \frac{\frac{4}{9}}{8} hei hautanga kotahi.

$$25-\frac{4}{9\times 8}+28$$

Whakareatia te 9 ki te 8, ka 72.

$$25-\frac{4}{72}+28$$

Whakahekea te hautanga \frac{4}{72} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$25-\frac{1}{18}+28$$

Me tahuri te 25 ki te hautau \frac{450}{18}.

$$\frac{450}{18}-\frac{1}{18}+28$$

Tā te mea he rite te tauraro o \frac{450}{18} me \frac{1}{18}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{450-1}{18}+28$$

Tangohia te 1 i te 450, ka 449.

$$\frac{449}{18}+28$$

Me tahuri te 28 ki te hautau \frac{504}{18}.

$$\frac{449}{18}+\frac{504}{18}$$

Tā te mea he rite te tauraro o \frac{449}{18} me \frac{504}{18}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{449+504}{18}$$

Tāpirihia te 449 ki te 504, ka 953.

$$\frac{953}{18}$$

Tauwehe

$$\frac{953}{2 \cdot 3 ^ {2}} = 52\frac{17}{18} = 52.94444444444444$$
