Whakaoti i te 72div4div2=3*xdiv5

$$72 \div 4 \div 2 = 3 \times x \div 5$$

Whakaoti mō x

$$x=15$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 10, arā, te tauraro pātahi he tino iti rawa te kitea o 2,5.

$$5\times \frac{72}{4}=2\times 3x$$

Whakawehea te 72 ki te 4, kia riro ko 18.

$$5\times 18=2\times 3x$$

Whakareatia te 5 ki te 18, ka 90.

$$90=2\times 3x$$

Whakareatia te 2 ki te 3, ka 6.

$$90=6x$$

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

$$6x=90$$

Whakawehea ngā taha e rua ki te 6.

$$x=\frac{90}{6}$$

Whakawehea te 90 ki te 6, kia riro ko 15.

$$x=15$$
