$$0.9 \times \frac { 5 } { 6 } \times 3 \frac { 1 } { 3 }$$

Aromātai

$$2.5$$

Ngā Upane Otinga

Me tahuri ki tau ā-ira 0.9 ki te hautau \frac{9}{10}.

$$\frac{9}{10}\times \frac{5}{6}\times \frac{3\times 3+1}{3}$$

Me whakarea te \frac{9}{10} ki te \frac{5}{6} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{9\times 5}{10\times 6}\times \frac{3\times 3+1}{3}$$

Mahia ngā whakarea i roto i te hautanga \frac{9\times 5}{10\times 6}.

$$\frac{45}{60}\times \frac{3\times 3+1}{3}$$

Whakahekea te hautanga \frac{45}{60} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 15.

$$\frac{3}{4}\times \frac{3\times 3+1}{3}$$

Whakareatia te 3 ki te 3, ka 9.

$$\frac{3}{4}\times \frac{9+1}{3}$$

Tāpirihia te 9 ki te 1, ka 10.

$$\frac{3}{4}\times \frac{10}{3}$$

Me whakarea te \frac{3}{4} ki te \frac{10}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{3\times 10}{4\times 3}$$

Me whakakore tahi te 3 i te taurunga me te tauraro.

$$\frac{10}{4}$$

Whakahekea te hautanga \frac{10}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{5}{2}$$

Tauwehe

$$\frac{5}{2} = 2\frac{1}{2} = 2.5$$
