$$- \frac { 50 } { 7 } + \frac { 53 } { 14 } \times 26 - 17$$

Aromātai

$$\frac{520}{7}\approx 74.285714286$$

Ngā Upane Otinga

Tuhia te \frac{53}{14}\times 26 hei hautanga kotahi.

$$-\frac{50}{7}+\frac{53\times 26}{14}-17$$

Whakareatia te 53 ki te 26, ka 1378.

$$-\frac{50}{7}+\frac{1378}{14}-17$$

Whakahekea te hautanga \frac{1378}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{50}{7}+\frac{689}{7}-17$$

Tā te mea he rite te tauraro o -\frac{50}{7} me \frac{689}{7}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-50+689}{7}-17$$

Tāpirihia te -50 ki te 689, ka 639.

$$\frac{639}{7}-17$$

Me tahuri te 17 ki te hautau \frac{119}{7}.

$$\frac{639}{7}-\frac{119}{7}$$

Tā te mea he rite te tauraro o \frac{639}{7} me \frac{119}{7}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{639-119}{7}$$

Tangohia te 119 i te 639, ka 520.

$$\frac{520}{7}$$

Tauwehe

$$\frac{2 ^ {3} \cdot 5 \cdot 13}{7} = 74\frac{2}{7} = 74.28571428571429$$
