Whakaoti i te 314=1div3*3.14*25*x

$$314=1 \div 3 \times 3.14 \times 25 \times x$$

Whakaoti mō x

$$x=12$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me tahuri ki tau ā-ira 3.14 ki te hautau \frac{314}{100}. Whakahekea te hautanga \frac{314}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$314=\frac{1}{3}\times \frac{157}{50}\times 25x$$

Me whakarea te \frac{1}{3} ki te \frac{157}{50} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$314=\frac{1\times 157}{3\times 50}\times 25x$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 157}{3\times 50}.

$$314=\frac{157}{150}\times 25x$$

Tuhia te \frac{157}{150}\times 25 hei hautanga kotahi.

$$314=\frac{157\times 25}{150}x$$

Whakareatia te 157 ki te 25, ka 3925.

$$314=\frac{3925}{150}x$$

Whakahekea te hautanga \frac{3925}{150} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$314=\frac{157}{6}x$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$\frac{157}{6}x=314$$

Me whakarea ngā taha e rua ki te \frac{6}{157}, te tau utu o \frac{157}{6}.

$$x=314\times \frac{6}{157}$$

Tuhia te 314\times \frac{6}{157} hei hautanga kotahi.

$$x=\frac{314\times 6}{157}$$

Whakareatia te 314 ki te 6, ka 1884.

$$x=\frac{1884}{157}$$

Whakawehea te 1884 ki te 157, kia riro ko 12.

$$x=12$$
