Whakaoti i te 3/5div7/10*(-15/9)=

$$\frac { 3 } { 5 } \div \frac { 7 } { 10 } \times ( - 1 \frac { 5 } { 9 } ) =$$

Aromātai

$$-\frac{4}{3}\approx -1.333333333$$

Ngā Upane Otinga

Whakawehe \frac{3}{5} ki te \frac{7}{10} mā te whakarea \frac{3}{5} ki te tau huripoki o \frac{7}{10}.

$$\frac{3}{5}\times \frac{10}{7}\left(-\frac{1\times 9+5}{9}\right)$$

Me whakarea te \frac{3}{5} ki te \frac{10}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{3\times 10}{5\times 7}\left(-\frac{1\times 9+5}{9}\right)$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 10}{5\times 7}.

$$\frac{30}{35}\left(-\frac{1\times 9+5}{9}\right)$$

Whakahekea te hautanga \frac{30}{35} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{6}{7}\left(-\frac{1\times 9+5}{9}\right)$$

Whakareatia te 1 ki te 9, ka 9.

$$\frac{6}{7}\left(-\frac{9+5}{9}\right)$$

Tāpirihia te 9 ki te 5, ka 14.

$$\frac{6}{7}\left(-\frac{14}{9}\right)$$

Me whakarea te \frac{6}{7} ki te -\frac{14}{9} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{6\left(-14\right)}{7\times 9}$$

Mahia ngā whakarea i roto i te hautanga \frac{6\left(-14\right)}{7\times 9}.

$$\frac{-84}{63}$$

Whakahekea te hautanga \frac{-84}{63} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 21.

$$-\frac{4}{3}$$

Tauwehe

$$-\frac{4}{3} = -1\frac{1}{3} = -1.3333333333333333$$
