$$- \frac { 13 } { 17 } \times 19 - \frac { 13 } { 17 } \times 15$$

Aromātai

$$-26$$

Ngā Upane Otinga

Tuhia te -\frac{13}{17}\times 19 hei hautanga kotahi.

$$\frac{-13\times 19}{17}-\frac{13}{17}\times 15$$

Whakareatia te -13 ki te 19, ka -247.

$$\frac{-247}{17}-\frac{13}{17}\times 15$$

Ka taea te hautanga \frac{-247}{17} te tuhi anō ko -\frac{247}{17} mā te tango i te tohu tōraro.

$$-\frac{247}{17}-\frac{13}{17}\times 15$$

Tuhia te \frac{13}{17}\times 15 hei hautanga kotahi.

$$-\frac{247}{17}-\frac{13\times 15}{17}$$

Whakareatia te 13 ki te 15, ka 195.

$$-\frac{247}{17}-\frac{195}{17}$$

Tā te mea he rite te tauraro o -\frac{247}{17} me \frac{195}{17}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-247-195}{17}$$

Tangohia te 195 i te -247, ka -442.

$$\frac{-442}{17}$$

Whakawehea te -442 ki te 17, kia riro ko -26.
