Whakaoti i te 2840/1=P*16*5/100*2

$$\frac { 2840 } { 1 } = \frac { P \times 16 \times 5 } { 100 \times 2 }$$

Whakaoti mō P

$$P=7100$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Ka whakawehea he tau ki te tahi, hua ai ko ia anō.

$$2840=\frac{P\times 16\times 5}{100\times 2}$$

Me whakakore tahi te 2\times 4\times 5 i te taurunga me te tauraro.

$$2840=\frac{2P}{5}$$

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

$$\frac{2P}{5}=2840$$

Me whakarea ngā taha e rua ki te 5.

$$2P=2840\times 5$$

Whakareatia te 2840 ki te 5, ka 14200.

$$2P=14200$$

Whakawehea ngā taha e rua ki te 2.

$$P=\frac{14200}{2}$$

Whakawehea te 14200 ki te 2, kia riro ko 7100.

$$P=7100$$
