$$\frac { 2 x - 8 } { 9 } \cdot \frac { 7 } { 8 x - 32 }$$

Aromātai

$$\frac{7}{36}\approx 0.194444444$$

Ngā Hipanga Rongoā Poto

Me whakarea te \frac{2x-8}{9} ki te \frac{7}{8x-32} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{\left(2x-8\right)\times 7}{9\left(8x-32\right)}$$

Me whakatauwehe ngā kīanga kāore anō i whakatauwehea.

$$\frac{2\times 7\left(x-4\right)}{8\times 9\left(x-4\right)}$$

Me whakakore tahi te 2\left(x-4\right) i te taurunga me te tauraro.

$$\frac{7}{4\times 9}$$

Whakareatia te 4 ki te 9, ka 36.

$$\frac{7}{36}$$

Tauwehe

$$\frac{7}{2 ^ {2} \cdot 3 ^ {2}} = 0.19444444444444445$$
