Whakaoti i te (13)(6/7)(-56/36)=

$$( 13 ) ( \frac { 6 } { 7 } ) ( \frac { - 56 } { 36 } ) =$$

Aromātai

$$-\frac{52}{3}\approx -17.333333333$$

Ngā Upane Otinga

Tuhia te 13\times \frac{6}{7} hei hautanga kotahi.

$$\frac{13\times 6}{7}\times \frac{-56}{36}$$

Whakareatia te 13 ki te 6, ka 78.

$$\frac{78}{7}\times \frac{-56}{36}$$

Whakahekea te hautanga \frac{-56}{36} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{78}{7}\left(-\frac{14}{9}\right)$$

Me whakarea te \frac{78}{7} ki te -\frac{14}{9} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{78\left(-14\right)}{7\times 9}$$

Mahia ngā whakarea i roto i te hautanga \frac{78\left(-14\right)}{7\times 9}.

$$\frac{-1092}{63}$$

Whakahekea te hautanga \frac{-1092}{63} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 21.

$$-\frac{52}{3}$$

Tauwehe

$$-\frac{52}{3} = -17\frac{1}{3} = -17.333333333333332$$
